紧邻建筑土质滑坡治理工程设计与实践
摘要:滑坡工程位于北京门头沟区,主要由人工填土及粗粒混合土组成,由于坡脚开挖及地表水渗入导致坡顶裂缝、变形明显且持续扩大,形成牵引式滑坡。通过对其特征、成因分析,并在土工试验基础上对滑带剪切参数进行反演计算,采用极限平衡法进行滑坡稳定性分析,提出采用抗滑桩+堑顶微型桩+坡面锚杆格构的综合治理措施。治理后滑坡变形得到控制,公路及坡脚建筑物得到安全保护,取得了良好的社会经济效益,以期对类似灾害治理工程有一定借鉴作用。
Abstract:A landslide project located in Mentougou, Beijing is mainly composed of artificial fill and coarse-grained mixed soil. Due to the excavation of the slope foot and the infiltration of surface water, the crack and deformation of the slope top are continuous expanding obviously, forming a traction landslide. Based on the analysis of the landslide characteristics and causes, inversion calculation of the shear test parameters is conducted on the basis of physical test, and limit equilibrium method is used to analyze the stability of the landslide. Anti-slide pile + top of cutting micro-pile + slope anchor rod lattice structure solution is proposed as a kind of comprehensive treatment measures to solve the landslide problem. After the treatment, the landslide deformation is controlled, and buildings near the road and slope-foot are protected. Good social and economic benefits have been achieved, at the same time it is expected to provide certain reference for similar disaster control project.
