文章借助Plaxis计算软件的动力模块,结合江苏省连云港某沿海高速公路工程,对软土地基上边坡稳定性进行了详细的研究分析。研究结论表明:边坡的开挖与堆载会导致公路路基孔隙水压力瞬时变形从而引起侧向位移,严重影响公路边坡安全稳定,且位移区域基本位于软土和表层土区域。
Combined with a certain coastal highway project in Lianyungang city, this paper analyzed slope stability of soft soil foundation by using the calculation software Plaxis power module. The results indicated that excavation and heaped load would lead to instantaneous deformation of pore water pressure for highway subgrade, and result in lateral displacement, which would seriously affect security and stability of highway slope. The displacement occurred basically in soft soil and topsoil region.
