南涪线沙溪沟滑坡是典型的路堑工程滑坡。定测阶段定性为一小型岩堆,施工图经济技术比较后采用清除处理,施工过程中路堑上方200外地面出现开裂,经过多次补勘确定为一大型古滑坡,严重威胁下方铁路的安全并影响南涪铁路的通车时间,经过有关专家多次会审以及多方案比选后,最终决定原位整治该滑坡。对南涪线沙溪沟滑坡产生的原因、稳定性进行了分析研究,提出了综合治理方案,工程治理效果良好,可为今后类似滑坡治理提供参考。
Nanxun Shaxigou landslide is a typical cutting engineering landslide. The determination stage is characterized by a small rock mass. After economic and technical comparison of the construction drawings, clearance treatment is adopted. During the construction, cracks occur on the outer surface of the top of the cut 200 and after many times make up a large ancient landslide, which seriously threatens the safety of the lower railroad Affect the Nan Fu railway opening hours, after many relevant experts meeting and multi-program comparison, the final decision to rehabilitate the landslide in situ. The reasons and stability of Shaxigou landslide in Nanfu Line are analyzed and studied. The comprehensive control plan is put forward and the project management effect is good, which can provide reference for similar landslide control in the future.
