摘要
采用一个考虑温度场和应力场耦合的三维强度折减有限元程序,探索变温在不同堤坝材料刚度情况下对堤坝稳定性安全系数的影响,用该程序计算结果表明,在堤坝材料弹模比较小时升温会使堤坝稳定性安全系数降低,在堤坝材料弹模比较大时升温会使堤坝稳定性安全系数增大。
The influence of change of temperature on the safety coefficient of stability of dam with different rigidities is studied by use of a program for the 3D finite element method （FEM） of strength reduction considering the coupling of temperature and stress fields. Through simulation with the program, the following result is gotten： the increase of dam＇s temperature can make the safety coefficient of dam stability decrease if the elastic module of dam is rather small, but the increase ofdam＇s temperature can make it decreases if the module is rather big.
