摘要
桥址高陡岩质斜坡稳定性分析时,一方面,应考虑斜坡的卸荷变形影响;另一方面,作为桥梁建设场地,除应评价其整体稳定性外,还应考虑表层危岩体及岩体蠕变对桥梁安全的影响。结合工程实例介绍了平硐所揭示的高陡岩质斜坡中的强烈卸荷变形特征,提出了桥址高陡岩质斜坡稳定性分析时应评价的内容及分析方法,对相似工程具有较好的借鉴作用。
When analysing the stability of hige-steep rock slope at a bridge site,we must consider the effects of unloading deformation,alse take into account of dangerous rock masses in surface and creep behavior of the rock mass,except for the whole stability of the slope.Based on a project,this paper introduces the strong unloading deformation in a high-steep rock slope,disclosed by some adits,brings forward the analysis content and methods as studing the stability of high-steep rock slopes.This paper can provide reference for similar projects.
