某岩质边坡稳定性分析及支护效果有限元评价

Stability Analysis and Evaluation of Retaining Effect for a Rock Buildings Slope

从基本地质条件出发,分析并计算贵阳某新建小区房建边坡典型断面的稳定性,采用钢筋混凝土抗滑桩对边坡进行支护设计,并用ADINA有限元方法验证了支护效果。有限元分析结果表明:支护后边坡开挖面最大位移减小了40%,应力、应变分布状态明显好于支护前,说明支护取得了很好的效果。

According to the basic geological conditions, tial building in Guiyang was analyzed and calculated. It the stability of construction slope nearby a new residen- is determined that reinforced concrete anti-sliding piles are used as a retaining measure and are designed, which are checked by ADINA of FEM software. The finite ele- ment analysis results show that after retaining the maximum displacement decreases by nearly 40% on excavation face of the slope and the stress and strain distribution is in a better state, which indicates that the retaining meas- ure has achieved good results.
