摘要
本文利用有限元计算软件,运用强度折减法,对苏洼龙水电站厂房后边坡进行应力应变分析计算,并探讨弹性模量和泊松比对边坡应力应变及稳定安全系数的影响,得出结论:弹性模量的性质决定其对应变的影响很大,但对应力和边坡稳定安全系数影响较小;泊松比对应力和应变影响均较小,但较小的泊松比对边坡稳定安全系数影响较大。
Finite element software is utilized in the paper.Strength subtraction method is adopted for analyzing and calculating stress and strain on slopes behind Suwalong Hydropower Station workshop.The influence of elastic modulus and poisson ratio on slope stress and strain as well as stability safety coefficient is discussed.The following conclusions are obtained：the nature of the elastic modulus determines that it has severe influence on strain,and slight influence on stress and slope stability safety coefficient.The poisson ratio has slight influence on stress and strain,but smaller poisson ratio has more influence on slope stability and safety factor.
