沥青混凝土心墙坝三维有限元静动力分析
3D FE static and dynamic analysis of rockfill dam with asphalt concrete core
摘要
Abstract
In order to study the static and dynamic characteristics of homogeneous rockfill dams with asphalt concrete core,the nonlinear three-dimensional finite element method was employed.Filling and storing processes of the dam were simulated,and the dynamic response of the dam was also got considering the influences of height of the dam,dynamic shear modulus,peak acceleration and seismic waves on the maximum dynamic shear strain of the core.The distribution of the stress,deformation and dynamic shear strain of the core were summed up.The results show that the top,bottom and abutment regions of the core should be paid more attention to and high core will be under more unfavorable conditions in static state, especially in full storage period. Under the action of earthquake,the dynamic shear strain at the top of core of central valley is the largest,but the value is small,less than 0.5%.关键词
