| 摘 要： | 利用有限元法,通过强度折减来求边坡稳定安全系数。基于ANSYS平台,采用有限元强度折减法分析重庆一工程边坡,得到边坡内部应力、应变滑动位置图及稳定系数。结果表明:边坡在旱季其稳定系数为1.36,边坡稳定;在雨季其稳定系数为1.03,边坡近于失稳状态,施工时应采取相应工程措施,以策安全。

| Abstract: | Slope stability coefficient is sought based on strength reduction of finite element method.In this paper,an engineering slope in Chongqing is analyzed using strength reduction finite element method based on ANSYS platform.The inner stress,strain and sliding position and stability coefficient are obtained.It is indicated that the stability coefficient of this slope in dry season is 1.36,trend to stable and that in rainy season is 1.03,trend to unstable.The corresponding engineering measures shall be taken un... |
