Abstract:

Compte tenu de la nature des sols, des incertitudes sur leurs propriétés sont largement rencontrées en géotechnique, en particulier dans le domaine des barrages en terre. Actuellement, il est de plus en plus nécessaire de tenir compte de ces incertitudes pour l'évaluation de la sécurité des grands barrages, notamment dans le cadre des études d’analyse de risques. Cependant, les analyses probabilistes sont complexes et difficiles à mettre en œuvre en raison du nombre limité de mesures, des temps de calcul importants et des limites des méthodes fiabilistes implémentées dans les outils de simulat

Abstract:

In zoned dams, it is expected that pore pressure is uniformly dissipated from the upstream to the downstream side of the core. Based on this hypothesis, the potential profile across the core in a steady state seepage flow is expected to be more or less linear and the equipotential lines should be distributed quasi-uniformly. This analysis is based on a homogeneous saturated permeability throughout the core. For some large cores made of glacial moraine (till), it has been reported that the pore pressures were significantly in excess of expected values during and after reservoir filling. The ma

Abstract:

An earth dam and a dike is one kind of hydraulic construction, which is built with highly compacted earth and can be used for the purpose of containing water in a reservoir to secure the water supply, and in flood control. Earth dam and dike can be a safety issue, as it can experience catastrophic destruction due to the slope failure caused by various factors, such as construction materials, vegetation, atmospheric conditions and so on. The aim of this study is to investigate the influence of the saturation degree (or water content) on the stability of earth dam and dikes under the considerati

Abstract:

It is estimated that 3,700 major dams are either planned or under construction, notably in developing countries. Dams can pose a threat to fish diversity, as one of the biggest impacts of damming is habitat fragmentation. Damming causes the isolation of small fish habitats, which reduces genetic diversity and expose fish species to vulnerability of local extinction, hence habitat fragmentation is one of the causes of biological loss. There are tools, which are used to balance between development and biodiversity conservation. One of the tools, which is commonly used, is environmental impact as

Diplomová práce představuje vytvoření softwarového 2D MKP modelu přehrady Slezská Harta v České Republice za pomoci softwaru PLAXIS 2D. V úvodu práce je analýza vodní nádrže, vytvořené jako zásobárna vody a protipovodňové dílo. Analýza sleduje geomorfologii, geologii, konstrukci tělesa hráze, použité materiály a metody, a stávající monitorovací zařízení. Pro pochopení tvorby 2D MKP modelu jsou předloženy a definované metody použitých analýz - metoda konečných prvků, analýza prosakování, materiálové modely, citlivostná analýza. Následně byla definována tvorba struktury modelu - určení posloupno

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>O presente trabalho apresenta o desenvolvimento de um procedimento numérico para a análise sequencial estática e dinâmica de barragens de terra, durante as principais fases da vida da estrutura:construção, enchimento do reservatório e carregamentos sísmicos. A modelagem numérica é feita mediante o método dos elementos finitos, incorporando as não linearidades dos materiais através de módulos dependentes do nível de tensões, para a análise estática, e do nível de deformações para a análise dinâmica.

碩士<br>逢甲大學<br>土木及水利工程所<br>90<br>We have got the monitoring datas of Nanhau earth dam. According to these monitoring datas. We got the distributions of the total head pressure and pore pressure. This study we used software package Seep2D model of the GMS to simulate stable type seepage. We compared and explored each other crossly by the results of simulations and monitoring datas. In order to understand the differences by this two datas. The results of the simulations and monitoring datas are almost the same at up and down stream. But the errors reach to 13% at the central parts of the earth da

In recent seismic safety evaluation of a reservoir,we mainly use pseudo-static analysis,which use a safety factor to represent a dam''s safety.But actually,the risk and uncertainty in any construction is inevitable.So,in the paper,we plan to use risk analysis to evaluate seismic safety of a reservoir and try t

碩士<br>國立臺北科技大學<br>土木與防災技術研究所<br>91<br>The demand for water used for living and industry is rapidly increasing in Taiwan. It’s necessary to build the additional reservoirs to expand the water resource. The earthquakes in Chi-Chi and Chiayi have caused various levels of damage to the local concrete and the earth dams. Fortunately, there were no serious failures to the local earth dams due to the last two earthquakes. The earth dams could be damaged and not withstand the next larger earthquake. In this research, the results of geotechnical engineering centrifuge model testin

And it is the indication of the dam safety assessment. The actually seepage volume be affected by the reservoir elevation and precipitation, but dam safety is no relation with the seepage be affected by precipitation. The study use the new way to improve the seepage monitoring devices during initial rising of reservoir water elevation（1996/9-2006/4）,let the device avoid the caco3 in water an
