重庆大水井崩滑体灾害防治技术研究

针对大水井崩滑体灾害急需治理的现状，对该崩滑体的变形特征等进行了研究。结果表明:大水井崩塌体中1号变形区的“强变形区”滑面已经形成，在地表裂缝密集区域已经贯通，“弱变形区”滑面尚未形成；在工况1条件下，1号和2号变形体均处于稳定状态，在工况2条件下，1号变形体处于欠稳定—基本稳定状态，2号变形体处于基本稳定状态；崩塌体后侧的陡斜坡在天然少雨条件下处于基本稳定状态，在强降水的冲刷下该斜坡中极易再次发生坡面水（泥）石流；建议采用“方案4:搬迁避让+斜坡绿化+修缮截（排）水沟”的治理方案。

Study on prevention and control techniques of landslide disaster in Dashuijing Area of Chongqing

In view of the situation that the slumped mass in Dashuijing is in urgent need of treatment，the deformation characteristics of the landslide were studied.The results showed that in the collapse body of Dashuijing，the "strong deformation zone" slip surface has been formed in the No.1 deformation zone，which has been connected in the surface fracture dense area，and the "weak deformation zone" slip surface has not been formed yet.Under working condition 1，both No.1 and No.2 deformable bodies are in stable state.Under working condition 2，the No.1 deformable body is in understable—basically stable state，and the No.2 deformable body is in basically stable state.The steep slope behind the collapse is in a basically stable state under the condition of natural little rainfall，and it is easy to cause slope water （rock） to flow again under the scour of heavy rainfall.It was suggested to adopt the treatment plan of "Plan 4:relocation and avoidance + slope greening + repairing and cutting （drainage） ditches".
