Finite Element Simulation Analysis for Concrete Arch Dam of Menkanshao Reservoir

The loads on the arch dam and the materials physical properties of the dam and the bedrock are uncertain, and can be described with random variable.Due to the huge volume, the complex structure of the dam and excessive random variable, the static analysis of the dam is difficult.The dam is a higher order statically indeterminate structure, and the variation of the temperature obviously affects the stress and displacement of the structure, therefore, it is very important to consider the randomness of the temperature change load in the static analysis of arch dam.Concrete arch dam is a common hydraulic structures, using finite element method threshold whistle singles concrete arch dam reservoir finite element analysis to calculate the arch in normal operation phase maximum stress and deformation.The results were analyzed and explained, singles concrete arch dam design and construction to provide a certain reference value.
