General situations of engineering geologic conditions of Longtan Hydropower Station

This article fully describes the engineering geological conditions of Longtan Hydropower Station, the high slope geological conditions and some countermeasures, on the basis of a large number of geological explorations on the dam site area of Longtan Hydropower Station on the characteristics of the rock mass mechanics, the stability of the surrounding rocks of the large underground cavities, the stability of high slope around the structures, the geological conditions of the left bank creep rock masses and the natural building materials further more. It puts forward some suggestions on the layout of dam axis, dam foundation excavation, the stability and supporting of the surrounding rocks of cavities and the slope excavation. The construction of Longtan Hydropower Station is carrying out smoothly.
