STABILITY ANALYSIS AND TREATMENT OF MUGUAGOU LANDSLIDE IN GUSHAN HYDROPOWER STATION OF HANJIANG RIVER

Site development a landslide in rural resettlement point on Muguagou village of Gushan Hydropower Station of Hanjiang river, the terrain of the site is slope terrain, Limited by scale of terrain and immigration, residents need to be placed on the landslide, this need to take the landslide to take measures for engineering control. A lot of work including surface mapping, exploration, geotechnical testing, etc, showed that: the landslide volume is about 11104m3, for middle scale rock mass shear landslide, status stability is better. By comparison, the engineering control of the way of cutting slope reduction and the foot in foot is put forward, the stability coefficient of landslide after engineering treatment meets the standard requirement. The results can provide technical support for the project construction and reference for the similar projects.
