摘　　要：根据计算力学和土工计算的原理,计算坝坡稳定,为砾石土心墙风化料坝在已确定坝体坡度的前提下,分析其坝体的安全稳定性。利用AutoBank7.7、Ansys大型有限元软件和U-mat材料本构模型程序,进行砾石土心墙土石坝的非线性有限元应力应变分析,从而求得坝体承受的应力及变形情况。经计算,结果表明:在已确定坝体坡度前提下该坝体的安全稳定性是满足要求的,无需放缓坝坡比例。以上的研究方法可为类似工程提供参考。According to the principles of computational mechanics and geotechnical calculations,the dam slope stability is calculated.On the premise that the slope of the dam body has been determined,the safety and stability of the dam body are analyzed for the weathered material dam of the gravel soil core wall.Using AutoBank7.7,Ansys large-scale finite element software and U-mat material constitutive model program,the nonlinear finite element stress-strain analysis of gravel-soil core wall earth-rock dam is carried out.Thereby,the stress and deformation of the dam body can be obtained.After calculation,the results show that the safety and stability of the dam body can meet the requirements under the premise that the slope of the dam body has been determined,and there is no need to slow down the proportion of the dam slope.The above research methods can provide reference for similar projects.
