Full textA triple tube wireline core barrel allowed to retrieve PQ3 and ZQ3 calibre samples from the foundation glacial till of the Jules-Allard dam, South of Quebec. Cross-hole testing allowed to obtain Young's modulus ranging from 1300 to 2600 MPa. Consolidated-undrained triaxial monotonic testing, yielded Young's modulus Emax ranging between 290 MPa and 6000 MPa, notably as a function of the amount of gravel particles present in the samples. ZQ3 samples Young modulus were similar to those obtained using the cross-hole testing. In addition, the Poisson's ratio of these samples were regularly zero. During cyclic triaxial testing, contraction was followed by dilation when the samples reached a phase transformation point and the stress path intersected the stress path of a monotonically loaded sample having the same effective consolidation stress. keywords: phase transformation, cyclic behaviour, glacial till, Young's modulus, shear wave velocity, Poisson's ratio.

Full textThis thesis contributes to the field of numerical modeling of the influence of heterogeneity on the hydro-thermal behavior of an embankment dam. The layering saturated hydraulic conductivities are estimated by the geostatistical method with the consideration of spatial continuities of fines content, water content and dry density. The lower values of hydraulic conductivities in the downstream portion of the core are provided from the numerical study on the dissolution, transportation, exsolution and diffusion of the gas at the upstream boundary. The predicted saturated hydraulic conductivities as well as the lower value of unsaturated hydraulic conductivities in the downstream portion are used as input parameters in the numerical simulation of heterogeneous influence. Five parametric studies performed with presence of one or more layers within the core with increased values of hydraulic conductivity are simulated in numerical models to investigate the influence from variable values of hydraulic conductivities as well as the changing locations and thickness of pervious layers on the thermal response. The numerical model also simulates the monthly thermal response of the core, which reveals the existence of another more pervious zone in the lower portion of the core.

Full textThe resistance of Romaine 3 till was studied under cyclic loading using a new cyclic simple shear apparatus. The tests were carried out at different compaction water contents (dry and wet sides of Proctor optimum) and at different cyclic shear stress levels. It was found that ten times more cycles were needed for samples compacted on the dry side of optimum to reach failure than for samples compacted on the wet side of optimum. It was also found that the tests carried out at low cyclic stress ratio took ten times more cycles to reach failure then tests carried out at high cyclic stress ratios. The presented research project is part of the NSERC – Hydro-Québec Industrial Research Chair in life cycle optimisation for embankment dams.

Full text345092\u Granular materials containing coarse particles are widely used in the large geotechnical works, such as embankments and dams. The investigation of the mechanical behavior of these materials requires large scale testing apparatus, resulting in costly and difficult testing programs. Therefore, in most of the current projects, the specimens with finer-grained materials having parallel grading and similar physical characteristics to original materials are prepared and the results directly used in the analysis and design of the structures. However, recent studies confirmed that the role of the particle size effect caused by using this technique should be considered. To improve understanding of this effect, in the first part of this study, the influence of particle size on the mechanical properties of filter materials of Romaine-3 dam is investigated through a series of the monotonic compression triaxial tests in the drained and undrained conditions as well as repeated-load triaxial (RLT) tests. The drained and undrained tests results showed that there is no change in the slope of CSLs in q-p’ space. The RLT test results also indicate that the load-unload modulus increases with increasing in particle size. Moreover, the shape of a particle has been identified as one of the most important parameters affecting the behavior of coarse materials. Thus, the second part consists of drained and undrained triaxial and RLT tests on filter and transition materials, having rounded and angular materials respectively, with different sizes in order to examine particle shape effect. The triaxial results show that the maximum stress ratio increases with increasing in the angularity, whereas the comparison of RLT results between the rounded and angular materials does not show any clear trend.

Full textAnalysis of high resolution bathymetric data and acoustic sub-bottom profiles acquired during the summers of 2014 and 2016 in the Manicouagan reservoir allowed the identification of numerous forms and sedimentary processes on the slopes and lake floor of former Lake Manicouagan. The following geomorphological analysis aims at better understanding the basin’s sedimentary dynamics following the deglaciation. Reaching 322 m deep, Lake Manicouagan was the deepest know lake east of the Great Lakes, before the flooding of the Manicouagan reservoir, whose depth now reaches 452 m. Lake Manicouagan can be divided into three areas: The north area, with a flat lake floor and steep slopes eroded by channels. The central area, where the deepest basins can be found. The south area, with an hummocky lake floor and gentler slopes, eroded by large gully systems. Before the flooding, sedimentary supply to the lake floor was dominated by river sources, through their deltas, and by gravity currents, causing the erosion of channels and gullies. The flooding of the reservoir caused a rise in the importance of mass movements in sedimentary transport to the lake floor, while eliminating river imput transport to the deep basins. The river sediments are now mostly deposited on the shelves and shores of the Manicouagan reservoir.

Full textRockfill dams are one of the most important structures in civil engineering. These are critical structures whose performance requirements are very high. In addition, the seismic standards for these structures have changed rapidly over the last few years (Hydro-Québec, 2003; Gouv.-du- Québec, 2002; Canadian Dam Association (CDA)) and currently are very sever. These analyzes are very important since they can define the behavior of structure when earthquakes happen, and consequently, evaluate its safety. However, these methods are complex and their application on existing dams is always a delicate exercise. Eastern Canada is characterized by an active but moderate seismicity. The earthquakes in Eastern Canada have a higher frequency content than the Western United States. Though, only a few studies have been made with signals from Eastern Canada. This thesis presents the results of the dynamic 1D and 2D behavior of a rockfill dam under seismic loading. The study takes into consideration the Denis-Perron dam activity, a rockfill dam of 171 meters height with a till core, which was finished constructing in 1998. This structure closes the Ste-Marguerite River on a narrow valley north of Sept-Îles. Recordings of accelerations at the top and at the base of the dam for three seismic events were used in different simulations. The 1D analyzes were conducted in the frequency domain with ProShake software. The 2D analyzes were conducted in the time domain with QUAD4M software, which adopts the linear behavior of soils, and FLAC, which takes into account the nonlinearity of soil behavior. For both analyses, the results were carried out in spectral and temporal domains. These results demonstrated that the 1D study on ProShake, with a correction of predominant period according to the shape of the valley, is necessary for preliminary dynamic studies of a dam. However, in depth studies, FLAC may be essential for seismic risk assessment of these structures

Full textHydroelectric reservoirs around the world are managed using hydrological models to calculate water inflows and outflows. Evaporation on these reservoirs is typically neglected or calculated in the same way as evapotranspiration over the entire watershed, although the processes governing the two phenomena are different. A better quantification of evaporation is of growing interest in Quebec and internationally due to climate change, which is causing an increase in water losses by evaporation on reservoirs. This study therefore examines various evaporation models for open water bodies, taking into account the practical context in which hydrological models are generally operated, that is with low availability of input data. The study focuses mainly on two reservoirs with contrasting morphometries and located in the Canadian boreal zone, Eastmain-1 and Romaine-2. For this purpose, a set of observed evaporation data obtained using a direct measurement technique called eddy covariance, is used as a reference. Of all the approaches considered, the mass transfer model with a constant Dalton number of 1.2 x 10⁻³ gives the most accurate estimation of evaporation at hourly time steps. Daily totals are also estimated with good accuracy both during the warming of the water body in spring and during the energy release period in fall. Sensitivity analysis show that the use of this model with limited data is possible, at least for the two reservoirs studied. These limited data consist of air temperature and relative humidity taken on land in the vicinity of the reservoir, water surface temperature measured in situ, and wind speed at a height of 10 m taken from the bank of the reservoir facing the prevailing winds. The application of the model on Lake Leman, located in a more temperate region, also gives good results.

Full textThe resolution of the problem of interaction gravel-asphalt in embankment dams with bituminous cores requires the knowledge of interfaces behavior between these two materials. This work is a contribution in this direction. Specimens were made in the laboratory using crushed stones owing a median particle size distribution and a characteristic asphalt of the Romaine 2. The direct shear device was used to perform the tests on these samples under a constant normal stress. In addition to the effect of applied normal stress, the influences of various parameters such as temperature, shear rate and the percentage of bitumen in the interface were explored. The major conclusion that can be drawn from these tests is that the behavior of the aforementioned interface is dominated by the asphalt and the failure envelope of this interface in conditions of very low shear rate or very high temperature, passes through the origin with a friction angle equal to 38.7 °. Keywords Interface; gravel-asphalt; direct shear; shear rate; temperature; failure envelope; ACRD.

Full textContact erosion is an internal erosion process that can be found in embankment dams and dikes which can lead to failure. It is defined as the pullout and dragging of fines from a base material through an adjacent coarser material under seepage parallel to the interface. This study intends to understand and to identify the mechanisms that control contact erosion with a well-graded base soil (Romaine 3 till) combined with different filter materials. To study the erosion process, a new experimental setup has been developed. Also, in order to properly assess the mechanisms involved with a well-graded base soil, comparative tests have also been performed with poorly-graded base soils. It was found that the grading of the base material as an important impact on the initiation and progression of contact erosion as different mechanisms such as paving and clogging can develop to limit or even stop the erosion. With the experimental results of this study as well as those found in the literature, a model for contact erosion threshold evaluation is proposed. Additionally, an experimental approach is proposed in order to simplify the study of contact erosion for well-graded base soils. Finally, a conceptualization of the erosion process (initiation and evolution) depending on the grain size of both filter and base soils and on the hydraulic solicitation is proposed. The Romaine 3 till susceptibility to contact erosion is assessed with latter conceptualization.

Full textThis dissertation studies the environmental dimension of CSR. Current issues raised by sustainability need to deconstruct the concept of CSR to reveal the underlying structure of the Business & Society academic field. Through historical and comparative approaches, this research follows the trail that socio-Environmental issues leave in the controversies they deploy, in the relationships they forge and in compromises they establish with human and non-Humans through the construction of four energy facilities in France (Tignes’ hydroelectric dam and La Rance’ tidal power plant) and Quebec (Bersimis’ hydroelectric dam and Gentilly’ nuclear plant) during the 1945th until the 1970th. In the line of work that develop non dichotomous understanding of the nature and culture by taking the refusal of Modern ontology (Latour; Descola; Gladwin, Kennely and Krause, and Banerjee etc.) as a base, it sheds light on associations/dissociations performed within heterogeneous group of allies and revisits "environmental turn" thanks to the precise analysis of the work of the founding father of CSR, Howard R. Bowen Social Responsibilities of the Businessman (1953), illuminating its theoretical legacies. This research aims at making three contributions. First, it refines the "naturalistic" approach or "Modern" in two empirical and cognitive perspectives and two modes of relating to collective: realism and nominalism. Then it entered the literature of CSR into the Modern ontology by showing theoretical legacies in wilderness conservation. Finally, it mobilizes the Amodern approach to analyze the socio-Environmental issues, and proposes an alternative understanding of CSR based on a dynamic and relational view of responsibility where the traditional boundaries of the business environment are broken in favor of socio-Environmental networks

Full textThis thesis contributes to the field of numerical modeling of rockfill dams during construction and impoundment based on laboratory research and field instrumentation. Data is presented from monotonic triaxial compression tests, in both stress and strain-controlled conditions, on compacted assemblages of granite rock particles prepared in the laboratory using different initial dry densities and grain size distribution. A nonlinear elastic-perfectly plastic constitutive model is implemented into the commercial software, FLAC, to simulate the behavior of the rock particles during the tests. The new implemented model is the traditional hyperbolic model coupled with the Mohr-Coulomb plastic failure criteria, and with a non-associated flow rule to consider shear dilatancy. The Nobari-Duncan stress relaxation technique with modified procedures and algorithms is also implemented in FLAC to reproduce the collapse deformations due to wetting. Using nine parameters, the model is successful to capture the observed behavior in the triaxial tests and to characterize the assemblage of rock particles. The effects of time and saturation are also discussed in detail. Finally, the model is used to simulate the construction and impoundment stages of LG4 rockfill dam in Quebec, Canada. The results of the modeling of both stages are compared with the instrumentation data and previous efforts of the modeling of this dam and the advantages of the new model are discussed.

Full textIn Quebec, the concrete dams over fifty years are systematically studied since the Saguenay earthquake (1988, 6.2 on the Richter scale) because they were not sized for such hazards. For calculation of the reliability codes for Hydro-Quebec structures, different parameters on the morphology of structure and the physical and mechanical parameters are needed. Among these, the shear strength of interfaces (concrete-concrete, concrete-rock rock-rock) is particularly important because it determines the safety factor in large part. Moreover, it is commonly accepted that the roughness of the surfaces of rock discontinuities determines the mechanical behavior in shear. This study is divided into two parts: a study of taking samples from two dams of Hydro-Quebec and the conception of an artificial rock-concrete contact. Firstly, from shear tests realized under constant normal load, achieved on contacts from two dams, the principal component study of mechanical and roughness parameters was conducted to determine the parameters dominate (Z2, Z4, Extent). In addition, a field classification of discontinuities is proposed. The latter depends on various parameters such as the angularity of the surface, filling or oxidation of the surfaces of the discontinuity. Artificial rock-concrete contact has been studied in its entirety by various statistical and geostatistical methods in order to describe as precisely as possible its surface roughness. Once the last known, a map of coring with a 150 mm diameter core sampler has been decided. The collected areas are those with features of roughness, for example, a high angularity. Once the coring performed, samples were tested for shear resistance under a constant normal load. It follows a study of mechanical and roughness parameter and an underline of scale effect

Full textThe event on which this thesis aims its focus is a topic of controversy in Quebec since 2006 : la Romaine, a hydroelectric complex involving the harnessing of one of the last great wild rivers in the province. Specifically, this study examines the new Innu and Quebecer institutional discourses on this project. The analysis takes as material of study the reports submitted to the consultation conducted in 2008 by the Bureau d’audiences publiques sur l’environnement (BAPE). Establishing a dialogue between ethnic studies, the concept of white settler colonialism and cultural studies, this paper sheds light on the role of the apparatus of sustainable development and of great dams in a colonial context. First, this research provides an historical framework on the renewal of the relationship between Quebec’s and Innu’s people centred, in turn, on agriculture, logging and large dams. The goal is to explain how this interethnic relationship, in constant metamorphosis, has been marked by different models of settling the territory. Secondly, this picture leads us to examine the socio-political situation from which emerges la Romaine. Following this contextualization, the application of a socio-technical grid of analysis allows to discover the ways in which sustainable development modulates the collective systems of representations in regards to interethnic relations and contemporary energetic regimes. This analysis expose simultaneously the regeneration of a settler’s imaginary for the Quebecers and the emergence of counter-discourses for the Innus. Ultimately, this research concluded by questioning the terms and possibilities of a decolonial sustainable development.
