Upstream tailings dams may experience slope stability problems when the rate of raising is too fast. Tailings consolidate slowly due to low hydraulic conductivity. The excess pore pressures can build up due to accelerated rate of raising. The cumulative increase ...

The present study concerns analysis of the seismic response of earth dams. The behaviour of both the shell and core of the dam is described using the simple and popular non associated Mohr-Coulomb criterion. The use of this constitutive model is justified ...

<p>No earthquake has caused failure or severe damage to any rockfill dams with bodies of well-compacted rock materials. It is important to estimate the damage grade quantitatively in order to evaluate a seismic performance of a dam against a large earthquake. ...

<p>The main concern when designing or analysing embankment dams is usually their stability. However, assessing their deformation is also important. This paper describes the recent use of advanced numerical analysis to predict the latter. Examples of its use ...

The technologies for construction of roller-compacted concrete (RCC) dams have been considerably developed during recent years in China. At the time being, they have been successfully applied to the constructions of even extreme-high gravity dams and medium ...

<p>The crack in concrete dam body is considered as a typical damage to concrete gravity dams during large earthquakes, and lots of researches on a nonlinear dynamic analysis method considering the occurrence and progress of cracks have been carried out in ...

A comparative study of temperature distribution in a roller compacted concrete dam during and after construction is carried out using two well known computers codes namely ANSYS and COSMOS. Two and threedimensional finite element models have been created and ...

The contact behavior between concrete face slab and dam body is important to the safety of concrete-faced rockfill dams. The deficient of dam body and the separation of concrete slab from cushion layer during construction and in operation are the main concerns. ...

<p>The increasing number of roller compacted concrete (RCC) dams being built around the world demands accurate methodologies for the realistic short- and long-term evaluations of the risk of thermally induced cracking in these constructions. In this work a ...
