摘要
鲤鱼塘水库溢洪道开挖边坡最大高度达到82 m左右,边坡的稳定将严重影响溢洪道乃至整个鲤鱼塘水库工程的运行.在分析边坡地质结构的基础上,提出了其变形失稳的几种模式破坏;针对不同的变形破坏模式,分别用刚体极限平衡法进行了稳定性计算和分析,对边坡不同变形破坏模式的稳定性进行了评价,提出了加固治理措施的建议,为边坡的加固治设计提供了理论依据.
The instability of the spillway excavating slope with a height of 82 m at in Liyutang Reservoir, exerts a tremendous influence on the spillway and the whole reservoir project. Based on the geological texture analysis, some kinds of deformation models have been built. In light of the different deformation models, the rigid body limit equilibrium method is used to calculate, analyze and evaluate the stabilities of the different areas. It provides scientific basis for administering the slope.
