摘要

通过位移计与三维扫描仪对海岛岩石陡坡进行实际位移监测与坡体轮廓的扫描

选取典型剖面

利用有限元强度折减法进行岩石陡坡的稳定性分析。提出了一种考虑降雨量对海岛斜坡稳定性影响的实用计算方法

并分析了降雨与坡脚开挖对边坡稳定性的影响

确定了典型剖面的最大降雨量与最大坡脚开挖量。在最大降雨量与最大坡脚开挖量情况下对典型剖面选取了三种支护方案

即锚杆（索）支护、抗滑桩支护、锚杆（索）与抗滑桩联合支护。利用有限元强度折减法进行不同支护方案下的有限元分析

对比稳定性安全系数、塑性区、应力与位移等信息

确定典型剖面的支护方式

并通过对锚杆（索）倾角与间距等支护参数的优化计算

得到了既安全又合理的海岛岩石陡坡支护方案。

Abstract

Based on the monitored displacement and scanned outline of island rock slope by displacement meter and 3dscanner

typical sections are selected and their stability is analyzed by the finite element strength reduction.A practical calculation method considering the effect of rainfall on the island slope stability is proposed.The effect of rainfall and toe cutting on slope stability is analyzed

and the maximum of rainfall and toe cutting for typical sections are determined.In this case

three support schemes are chosen for the typical sections

i.e.bolting support

anti-slide pile support

bolting and anti-slide pile combined support.Calculating analyses are carried out for different support schemes by using the finite element strength reduction.By comparing the safety factor of stability

plastic zone

and stress and displacement information under different support schemes

the support scheme is determined for typical sections.Finally

the economical and reasonable support scheme is obtained through the optimized calculation of some support parameters such as the dip angle

distance of bolt and anchor cable.
