摘要
The Guanyinyan Hydropower Station locates in the upper reaches of Jinsha River. On the basis of analyzing geological conditions and hydro-geological conditions in the right bank of the station, this paper investigates the groundwater-dynamic simulation, water-soluble element statistics and corrosion experiment of sampling for rock corrosion rules. It is found that the rock and tectonic control play a leading role for the rock corrosion. The solute reaction is developed intensely along strike direction of joints and fractures, because of local-groundwater with quick circle and rapid flow rate. The results can serve as the foundation for antiskid, distortion and seepage stability evaluation. They also provide background information for the study to erosion-dissolution of rock with groundwater after impounded water.
