摘要
文章以某膨胀土边坡为例,模拟边坡地下水渗流场稳态,并结合南京库伦GEO5的土质边坡稳定性计算模块对边坡进行稳定性分析.经计算,该边坡在降雨条件下,地下水位上涨至坡表及坡顶,稳定性也急剧下降;采用削坡清方措施后,边坡整体稳定性上升,再辅以截排水与圬工加固措施,可满足工程需求.
Abstract
Taking an expansive soil slope as an example,this paper simulates the steady state of groundwater seepage field of the slope,and analyzes the stability of the slope in combination with the soil slope stability calculation module of Nanjing Kulun GEO5.According to the calculation,under the condition of rainfall,the groundwater level of the slope rises to the surface and top of the slope,and the stability also decreases sharply;after the slope cutting and clearing measures are adopted,the overall stability of the slope increases,and then supplemented by interception drainage and masonry reinforcement measures,it can meet the engineering requirements.
