摘要
三峡库区巫山县四期移民工程建设中形成不少高边(切)坡,高边(切)坡可能存在的失稳、变形将威胁到新建城镇基础设施、建构筑物和人民生命财产的安全。现以巫山县城西部教师新村的一处高边(切)坡为例,探讨了高边(切)坡稳定性影响因素,采用极限平衡法及工程地质类比法等分析方法对其稳定性进行了计算分析和预测评价,并提出了"毛石混凝土挡土墙+削坡+混凝土格构锚杆支护+排水工程"的工程治理方案。
There are many high cut and fill slopes created in the Phase IV Immigration Project for the Three Gorges Reservoir affected areas in Wushan County. The instability or excessive deformation of these slopes might post a potential hazard to the safety of infrastructures, buildings and human life. This paper presents a case study of the stability evaluation of a high cut slope for the site of Western China Teacher＇s Residential Community in Wushan County. Factors that affecting the stability of this slope are discussed in the paper. The limit equilibrium and geological analogy methods are used in the stability evaluation and prediction work. The stability mitigation scheme is a combination of masonry gravity retaining wall, flattening slope, rein- forced concrete grid beams and installation of drainage system.
