某大型抗滑挡墙开裂原因分析及处置

Cracking cause analysis and treatment for a certain large anti-sliding wall

某滑坡前缘大型抗滑挡墙开裂变形诱因复杂。文章基于监测、施工、检测资料,综合分析认为某挡墙开裂系上部堆料产生的局部土体挤压剪切变形所致。堆载、施工弱面、墙后填料差、排水不畅等因素为直接诱因。采取了"锚固+排水+控制堆载+监测"的综合处理措施,效果良好。

The incentives of the cracking deformation are complex for the large anti-sliding wall at the front of a certain landslide. Based on the data of the monitoring, construction and testing, the paper considers the cracking of a certain anti-sliding wall is induced by the partial soil extrusion shear deformation generated by the upper stacker through the comprehensive analysis. The direct incentives are the factors of the heaping load, the weak surface construction, the bad filler after the wall and the poor drainage. The comprehensive treatment measures of the anchoring, drainage, heaping load control and monitoring are adopted to achieve the better result.
