Taiwan’s offshore wind farm industry is starting to launch, but lacked marine site investigation experiences and localized guideline in Taiwan. Therefore, how to establish the framework of offshore wind farm preparatory system and compose the site investigation guidelines which are suitable for Taiwan’s maritime environment and offshore wind farms become an important issue. This study was collected and discussed the codes or guidelines of international offshore wind farm site investigation, geotechnical design and EIA standard, including ABS, BV, BSH, DNV-GL, Euro code, IEC, NORSOK, SUT, and preparatory system including Denmark, UK, USA, Germany, China, HK, etc. This study also integrated the internal legislation or law and considering the local condition to propose the localized site investigation guideline for offshore wind farm and listed recommendations for preparatory system. Based on the related international codes and guidelines, this study was provided a suitable guideline of localized site investigation for offshore wind farm. This guideline not only explores the requirements to establish offshore wind farms, but also explains the details of site investigations such as geotechnical and geophysical survey. Specifically, this guideline combines those laws and standards; and makes it effective to Taiwan’s offshore wind industry. It could be improved the capacity of Taiwan’s offshore wind power development. As the basis of the important geotechnical parameters of offshore investigation suggestion by SUT and NORSOK standard, this study suggests several of essential geotechnical parameters and data which are necessary in the design phase. Research areas are situated in these four offshore wind farm areas, as Chang-Bin Fuhai phase II, the submarine cable route, and Si-Dao area. Collecting site investigation information, such as geophysics, geotechnical and drilling data, and the correlation of soil parameters and cone-penetration test data were discussed to establish geotechnical parameters and propose the suggestions for localization parameters. By using of the empirical formulas, this study shows most of the soil layers of site area are composed with sandy soils, and also has soft soil distribution. Besides, due to some deviations between the mean drilling data, laboratory tests are necessary to get accurate soil parameters, and should be aware of the risk of soft shallow soils in the maritine engineering of offshore wind farm. Keywords: offshore wind farm, preparatory system, site investigation guideline, geotechnical parameters, cone-penetration test (CPT)

Dividiu-se o trabalho em seis capítulos: o primeiro consiste numa introdução, na qual são descritos os objetivos do trabalho, bem como uma breve introdução histórica e um enquadramento geográfico e geológico; no segundo capítulo é descrito o enchimento aluvionar do Mondego tendo em conta as glaciações, a erosão e a ocupação humana da área em estudo; o terceiro capítulo é dedicado à descrição das técnicas de prospeção e a sua importância; no quarto capítulo descrevem-se os trabalhos de prospeção do Centro de Saúde Fernão de Magalhães tendo em conta as sondagens realizadas, o zonamento geotécnico atribuído e a arqueologia; no quinto capítulo apresentam-se várias condicionantes à realização do projeto, nomeadamente a presença de património arqueológico ou a falta de condições geológicas e geotécnicas para a realização do projeto; o último capítulo diz respeito às conclusões do trabalho.Reunindo as características geológicas e geotécnicas dos terrenos foi possível distinguir quatro unidades geotécnicas observadas. O zonamento geotécnico atribuído foi, unidade geotécnica UG1 – Aterro, UG2 – Aluvião, UG3 – Solo Argiloso e UG4 – Margas e Calcários. Deste zonamento geotécnico conclui-se que existem unidades geotécnicas que apresentam características não adequadas à construção de edifíciosDe acordo com as informações transmitidas pelo Arqueólogo Pedro Roquinho, se a fundação for realizada acima do nível arqueológico deverá ser necessário acompanhamento arqueológico na fase de execução das fundações. Caso se opte por fundações mais profundas deverá ser necessário realizar previamente sondagens arqueológicas. As decisões vinculativas serão da responsabilidade da Direção Regional de Cultura do Centro.
It is sought of this paper to provide an objective assessment of the geological and geotechnical conditions of the areas where will be the future Health Primary Care Center Fernão de Magalhães. The work was divided into six chapters: the first one is an introduction, in which the objectives of the work are listed, as well as a brief historical introduction and a geographic and geological framework; in the second chapter the river Mondego alluvial filler is described taking into account the glaciations, erosion and human occupation of the area under study; the third chapter is dedicated to the explanation of prospecting techniques as well as their importance; in the fourth chapter the exploration works of the Fernão de Magalhães Health Center are described, taking into account the surveys carried out, the assigned geotechnical zoning and archeology itself; in the fifth chapter presents the several constraints to the realization of the project, such as the presence of archaeological heritage or the lack of geological and geotechnical conditions for the realization of the project as it is; finally the last one it´s dedicate to the conclusions of the paper.By combining the geological and geotechnical characteristics of the lands, it was possible to distinguish four observed geotechnical units. The geotechnical zoning attributed was, geotechnical unit UG1 - Landfill, UG2 - Alluvium, UG3 – Clay Soil and UG4 - Marls and Limestone. From this geotechnical zoning it is concluded that there are geotechnical units that present characteristics that are not suitable for the construction of buildings.According to the information transmitted by the archaeologist Pedro Roquinho, if the foundation is carried out above the archaeological level, archaeological accompaniment should be necessary in the execution phase of the foundations. In case of deeper foundations, archaeological surveys must be carried out. The binding decisions shall be responsibility of the Regional Directorate of Culture of the Center.

Full textAlmost all natural soil and rock deposits are highly variable in their properties. Soil properties can vary by orders of magnitude from site to site, and even within a single site. As a result, the soil profiles cannot be identified with certainty, even if an extensive subsurface exploration program is executed. In most cases, measurements are only obtained from a limited number of site investigation tests at scattered locations over a construction site constrained by operational and economic considerations. Insufficient or inappropriate site investigation tests can lead to a range of undesirable consequences. Numerous geotechnical projects have experienced cost overruns, unexpected delays, and occasional failure due to unforeseen variability in the subsurface. It is of great significance to develop a design based on an effective site investigation that performs satisfactorily while providing an appropriate level of safety and minimizing the use of financial and human resources. This research proposed a framework which can quantify the benefits of undertaking site investigation of different sampling locations, increased scope and better testing methods. To assess the effectiveness of a site investigation, a simulated slope where the properties are known exactly at every location is used to act as a benchmark. The slope design based on the complete knowledge of the soil properties reflects the true state of the slope, which has only been possible due to the use of simulated soil properties. The site investigation is then carried out numerically at discrete locations from the simulated slope. The slope stability analysis based on the obtained measurements is performed by the finite element method. Such a design would be unreliable because the decision about the stability of slope is made on the basis of a set of samples. Comparisons between the designs based on complete and limited information indicate that two types of decision errors could be made due to inaccurately or inadequately site investigations. This comparison is repeated many times within a Monte Carlo framework to incorporate the uncertainties in the slope design process. Uncertainties due to inherent soil variability, measurement errors and limit measurements have been included. The Monte Carlo simulations have also provided the means to estimate the probabilities of decision errors by counting how many times the unreliable designs have been made based on limited site investigation measurements. Furthermore, the costs associated with the site investigations and making wrong decisions are assigned. It is then possible to assess the site investigation effectiveness through quantifying the relationship between various aspects of a site investigation and the corresponding cost and risk of slope design. The proposed framework enables the direct comparison of different sampling locations, numbers of the site investigation tests, and the testing methods. This allows the identification of optimal site investigation that provides a design with the lowest risk. Results indicated that there is an optimal sampling location that gives the most information while the probability of making the wrong decisions is a minimum. It also appears an optimal site investigation scope, beyond which the cost of additional samplings does not justify the cost savings due to reduced slope failure risk. However, if the cost of slope failure is high, increasing the scope of a site investigation will lead to a lower risk that is because the expected savings in terms of risk are significant when compared to the increased investigation cost. The proposed framework and those results would assist engineers in designing a more efficient and accurate, geotechnical site investigation.

Full textPile foundations are often used for important structures, and thus, reliability evaluation is an important aspect of the design. Unlike the approach to reliability evaluation used in structural engineering, the traditional procedure used in geotechnical designs addresses uncertainties through high global or partial safety factors, mostly based on past experience. However, this approach to addressing uncertainties does not provide a rational basis for understanding their influence on design. For this reason, and because of regulation codes and social concerns (such as sustainability), geotechnical engineers need to improve their ability to deal with uncertainties and probabilities to help with decision-making. Reliability methods have become increasingly important as decision support tools. The main benefit of reliability analysis is that it provides quantitative information about the parameters (uncertainties) that most significantly influence the behaviour under study. This makes risk control, the determination of the potential causes of adverse effects on the structure, possible. In particular, the design of pile foundations still involves many limitations and uncertainties, particularly when there is not enough investment in soil characterisation and/or pile load tests. In addition to the uncertainties associated with soil characterisation, physical, statistical, spatial and human uncertainties exist. Hence, because it is technically and economically impossible to produce designs of pile foundations in the most unfavourable of cases, it is the engineer’s goal to minimise the risk and limit it to an acceptable level in the most economical manner possible. Towards this, reliability theory needs to be adapted to the needs and objectives of geotechnical engineering. In this subject, the primary purpose of this dissertation is to demonstrate the application of reliability methods to geotechnical design and more particularly to two distinct case studies of vertical single pile foundations under axial loading. This dissertation also presents a simple and practical approach to performing reliability-based design, obtaining valuable information from it. For that purpose, sensitivity and cost analyses were conducted to study the influence of each uncertainty type. Two well-known reliability methods, the first-order reliability method (FORM) and Monte Carlo simulations (MCS) were applied to the case studies for comparison. In addition, reliability-based safety factors were evaluated and discussed. Another purpose of this dissertation is to demonstrate the advantages of employing reliability tools in the decision-making process for pile foundation design. The decision-making related to the economic and research investments required for gathering the information necessary to characterise the uncertainties associated with important random variables, in both pile design and its reliability, is facilitated by the type of balanced analyses presented in this dissertation. It is concluded that, even though the extent to which this can be accomplished depends on the engineer’s knowledge and the project’s budget for investigation, geotechnical engineering definitely benefits from the consideration of reliability in design. It is finally intended to provide knowledge and tools for code harmonisation between structural and geotechnical designs, and also encourage the development of such in geotechnical practice, international standards and conformity in assessment systems.
As fundações por estaca são utilizadas em obras de grande importância, e por esse motivo a fiabilidade na avaliação da segurança é um ponto essencial no seu dimensionamento. Ao contrário do que acontece em engenharia estrutural, a fiabilidade geotécnica é ainda obtida através de elevados coeficientes de segurança, globais ou parciais, na sua maioria com base empírica. No entanto, esta forma de tratar as incertezas não apresenta uma base racional para compreender a sua influência no dimensionamento e no projeto. Por estas razões, por questões de preocupação sociais (como a sustentabilidade) e também para obedecer às novas regulamentações, os engenheiros geotécnicos devem melhorar a sua capacidade para tratar as incertezas e gerir probabilidades, para que com isto possam ter ajuda nas tomadas de decisão. Os métodos de fiabilidade têm ganho uma importância crescente como ferramentas de ajuda e suporte a tomadas de decisão. As principais vantagens são a quantificação da probabilidade de ocorrência do comportamento da estrutura em estudo e a obtenção de informação sobre os parâmetros (incertezas) que mais o influenciam. Isto melhora o controlo do risco e a determinação das potenciais causas de efeitos adversos sobre a estrutura. Em particular, o dimensionamento de fundações por estaca ainda tem várias limitações e diversas incertezas, especialmente quando não existe investimento suficiente na caracterização do solo e/ou na realização de ensaios de carga. A esta incerteza no solo e seu comportamento, acrescentam-se ainda as incertezas físicas, estatísticas, espaciais e erros humanos. Assim, sendo tecnicamente e economicamente impossível fazer dimensionamentos considerando os casos mais desfavoráveis, é objetivo de um engenheiro minimizar e controlar os riscos a um nível aceitável da forma mais económica possível. Para tal a teoria da fiabilidade deve ser adaptada às necessidades e objetivos da engenharia geotécnica. Neste contexto, este trabalho pretende demonstrar como realizar análises de fiabilidade, introduzindo as incertezas no dimensionamento do ponto de vista geotécnico. Dois casos de estudo de duas fundações por estaca submetidas a carga axial são apresentados, explicando metodologias simples e práticas para realizar análises de fiabilidade, das quais um engenheiro pode obter informações valiosas e importantes. Para tal, análises de sensibilidade envolvendo as técnicas de fiabilidade e custos foram realizadas a fim de investigar a influência de cada parâmetro (incerteza) considerada. Dois métodos tradicionais de fiabilidade, o método de fiabilidade de primeira ordem (FORM) e o método de simulação de Monte Carlo (MCS), foram aplicados aos casos de estudo para comparação entre si. Além disso, coeficientes de segurança baseados nas técnicas de fiabilidade foram também avaliados e discutidos. Outro objetivo deste trabalho é demonstrar as vantagens da utilização das ferramentas de fiabilidade no processo de tomada de decisão no projeto e dimensionamento de fundações por estaca. As tomadas de decisão relativas a investimentos económicos e em investigação, necessários para a recolha de informação essencial para caracterizar as incertezas mais influentes, é facilitada com o tipo de análises apresentadas neste trabalho. Conclui-se portanto que, embora este tipo de investimento depende consideravelmente do conhecimento do engenheiro responsável e do orçamento disponível para a obra em questão, o projeto e dimensionamento iriam beneficiar notavelmente com este tipo de análises baseadas nas técnicas de fiabilidade. Finalmente, este trabalho é destinado a fornecer conhecimentos e ferramentas para a harmonização entre os dimensionamentos estrutural e geotécnico, e também incentivar o desenvolvimento destas técnicas na prática de geotecnia, na normalização internacional e na conformidade dos sistemas de avaliação.
