摘要
研究区为潜江洪荆线86^(#)桩附近一边坡,通过现场勘察、测绘等查明了边坡工程地质性质及坡体开裂变形特征。应用模拟软件建立场区地质力学模型,计算得出边坡安全系数,评价了边坡稳定性,分析了地下水渗流稳定性,结果表明:坡脚回填土不均匀沉降及挡土墙墙背回填土固结沉降导致坡顶开裂,对边坡整体稳定性无影响。可为类似工程边坡防治提供参考。
The study area is a slope near the 86^(#) pile on Hongjing line in Qianjiang,through on-site survey and mapping,the engineering geological properties of the slope and the characteristics of slope cracking and deformation have been verified.The geomechanical model of the site was established by using simulation software,the safety factor of the slope is calculated,the stability of the slope and groundwater seepage is evaluated.The results show that cracks are caused by uneven settlement of the backfill soil at the foot of the slope and the consolidation settlement of the backfill soil at the back of the retaining wall,which has no effect on the overall stability of the slope.The result can provide reference for slope prevention of similar engineering.
