| 摘 要： | 砾岩边坡稳定性影响因素众多,采用有限元强度折减理论对砾岩边坡稳定性影响因素进行数值分析研究,结果表明:砾岩弹性模量与泊松比对边坡安全系数影响很小,对极限状态下边坡的塑性区发展影响较大;强度参数内聚力和内摩擦角对边坡安全系数影响很大,安全系数与软弱层内聚力呈线性关系。

| Abstract: | The stability of conglomerate slope is influenced by many factors.This paper numerically analyszed the stability influencing factors of conglomerate slope by finite element strength reduction method.The results show that the elastic modulus and poisson’s ratio affect the safety factor lightly,but the plastic zone of limit equilibrium state may be intensity of stability of slope.The strength parameters of cohesion and friction angle affect intensity on safety factor of slope.It increases linear relationship between the safety factor and the cohesion of the weak layers. |
