摘要
强度折减方法是目前求解坝基抗滑稳定安全系数的常用方法。但在有限元计算中一般只对强度参数c,φ进行折减,没有考虑E,v的变化。怎样进行相应调整及是否需要做调整是一个悬而未决的问题。推导了应用不同屈服准则对应的各种材料参数之间应满足的关系,并针对某重力坝,利用ANSYS对材料E,v参数做调整及不做调整两种情况进行计算对比,为工程应用提供一定的参考。
The method of strength reduction is used widely in solving the anti -slide safety coefficient of the base of dam. However, scholars only consider the reduction of the strength parameters ,but little about modification. How to modify them and whether they should be modified havent been solved yet. This paper deduced the relationship between each material parameter according to different yield criterions by ANSYS, and analyzed and compared the anti - slide safety coefficients of a dam with and without modifying E,v, providing a basis to the application in engineering.
