摘要
基于拦石挡墙的抗滑移和抗倾覆稳定计算方法,以白庙子滑坡工程为例,选用36组不同抗剪强度指标的土体作为拦石挡墙的墙后填土,分析了填土强度对拦石挡墙稳定性的影响。计算结果表明,墙后填土的内聚力对拦石挡墙的稳定贡献很大,抗滑移和抗倾覆安全系数对墙后填土内聚力变化较内摩擦角变化更敏感。
Based on the method of stability calculation for anti-sliding and anti-overturning of stone falling wall,taking the Baimiaozi landslides project for an example,36 groups soil with different shear strength parameters are selected as the filled soil of barrier wall and used to analyze the influence of filled soil strength on stone falling wall stability.The calculation results show that shear strength of filled soil has great contribution to the stability;anti-slip and anti-overturning safety factors of barri...
