海岛岩石陡坡稳定性分析与支护方案优化计算
Stability Analysis of Island Rock Slope and Optimized Calculation of Support Schemes
摘要
Abstract
Based on the monitored displacement and scanned outline of island rock slope by displacement meter and 3d scanner,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 rea sonable support scheme is obtained through the optimized calculation of some support parameters such as the dip angle,distance of bolt and anchor cable.关键词
