摘要
为合理实现滑坡灾害防治,文中在勘查成果分析基础上,进行了滑坡防治工程设计,并结合变形监测成果,通过变形预测来开展防治效果评价。结果表明,在滑坡稳定性计算中,其稳定状态属不稳定-稳定状态,以暴雨工况的稳定性相对最差,两剖面剩余下滑力分别为18.95、16.43 kN/m。结合工程实际,将滑坡防治工程总体设计为挡墙+排水沟,排水沟位于挡墙脚部,均为两段,长度分别为42、52 m。经变形预测分析得出,其后续变形虽会增加,但趋于收敛,最终预测的变形值分别为16.34、14.16 mm,明显小于25 mm的控制值,说明滑坡防治达到了设计要求。
In order to achieve reasonable landslide disaster prevention and control,based on the analysis of exploration results,the landslide prevention and control engineering design was carried out in the article,and combined with deformation monitoring results,the prevention and control effect was evaluated through deformation prediction.The results show that the stability of the landslide is unstable to stable,and the stability of the rainstorm condition is the worst.The residual sliding forces of the two profiles are 18.95 and 16.43 kN/m respectively;Based on the actual engineering situation,the landslide prevention and control project is designed as a retaining wall+drainage ditch,with the drainage ditch located at the foot of the retaining wall.Both are divided into two sections,with lengths of 42 and 52 meters respectively;Through deformation prediction analysis,it is found that although the subsequent deformation will increase,it tends to converge.In addition,the final predicted deformation values are 16.34 and 14.16 mm,which are significantly less than the control value of 25 mm,indicating that landslide prevention and control have met the design requirements.
