本文主要阐述天生桥二级(坝索)水电站右岸~#1滑坡发生的地质背景,滑坡的分区及其形成机制分析,和滑坡的变形基本规律及其监测工作、滑坡的稳定分析,以及滑坡工程处理问题。该滑坡的工程处理措施有:在滑坡下方修筑混凝土挡墙,并在挡墙上设置锚杆和预应力锚索;在滑坡体上部减载和进行框架式护坡;地表设排水系统:地下设置由垂直深孔和水平排水廊道组成的排水孔幕。经2～3年的变形监测工作,滑坡已处于基本稳定状态,监测工作仍继续进行,此处理方法可供同类工程参考。
This paper mainly elaborates the geologic background of the landslide # ~ 1 on the right bank of the Tianshengqiao II (Baasuo) Hydropower Station, the analysis of the zoning and formation mechanism of the landslide, the basic rules of the deformation of the landslide and its monitoring, the stability analysis of the landslide and the landslide engineering treatment problem. The landslide works are: the construction of concrete retaining wall below the landslide, and in the retaining wall set anchor and prestressed anchor; in the upper part of the landslide load shedding and frame protection; surface drainage system: the ground set by the Vertical deep hole and horizontal drainage corridor composed of drainage hole curtain. After 2 ~ 3 years of deformation monitoring, the landslide has been basically stable and the monitoring work is still underway. This treatment method can be used for reference of similar projects.
