摘要
鉴于分析胶凝堆石坝结构缺少有效手段,利用ABAQUS的二次开发平台,开发了胶凝堆石料非线性弹性本构模型的UMAT用户子程序,提出了实现胶凝堆石坝的施工模拟及新填筑层位移修正的处理方法,并在两种工况下进行有限元模拟计算。结果表明,该方法合理可靠、符合实际工程规律。
As the structural analysis tool for cemented sand ＆ gravel dam is rare, by means of the ABAQUS secondary development platform, UMAT subroutine of nonlinear elastic constitutive model of cemented sand ＆ gravel material is developed. And the treatment method for construction simulation of the dam and correction the displacement of new filllayer is put forward. Then finite element simulation calculation of the dam are analyzed under two working conditions. The results show that the proposed method is reasonable and reliable, which accords with the actual engineering rules.
