摘要
为探讨高等级公路边坡治理方案的合理选择,以四川省眉山市新建某一级公路高边坡处治为例,通过调查工点处地质条件,依照路堑边坡开挖及变形情况,选用圆弧稳定分析方法Bishop法进行参数反演,定量对开挖后的路堑边坡进行稳定性分析,在此基础上提出桩板墙处治方案。当前该边坡治理已完成,工程交工进入通车运营阶段,抗滑桩桩顶位移监测数据收敛,表明边坡趋于稳定,抗滑桩治理方案有效。
In order to discuss the reasonable selection of high grade highway slope treatment scheme,taking the treatment of high slope of a newly-built first-class highway in Meishan City,Sichuan Province as an example,through investigating the geological conditions at the construction site,according to the excavation and deformation of the cutting slope,the circular arc stability analysis method—Bishop method is selected for parameter inversion,and the stability of the excavated cutting slope is analyzed quantitatively.Based on this,the treatment scheme of sheet pile wall is proposed.At present,the slope treatment has been completed,and the project has been put into operation.The monitoring data of the top displacement of the anti-slide pile converges,indicating that the slope tends to be stable and the anti-slide pile treatment scheme is effective.
