摘　　要：借助Abaqus有限元软件,研发低胶结砂石料应变预测模型的Umat子程序,进行竣工期与蓄水期低胶结砂石坝结构工作性态分析,研究结果表明,基于该新模型得出的低胶结砂石坝应力变形分布规律与其他学者得出的相应规律基本相同。研究成果可为低胶结砂石坝这一新坝型的结构设计提供一种新方法。With the help of ABAQUS finite element software, the UMAT subroutine of low Cemented Sandstone strain prediction model is developed to analyze the structural behavior of low Cemented Sandstone dam in the completion period and storage period. The research results show that the stress and deformation distribution law of low Cemented Sandstone dam based on the new model is basically the same as that obtained by other scholars. The research results can provide a new method or way for the structural design of low Cemented Sandstone dam.
