1 Project Overview Qihe plate stone reservoir is a large-scale comprehensive utilization of water conservancy project. The control basin area is 1915km ~ 2. In 2000, once a check flood level is 275.0m, the corresponding storage capacity is 608 million m ~ 3, the maximum dam height is 102.2m, and the total installed capacity of hydropower station is 10,000 kW. After the completion of the reservoir, 135 million m 3 of industrial and urban water can be supplied to Hebi City every year, and the existing irrigation area of 33,300 km 2 is replenished with 26.16 million kW · h of power from irrigation and water supply. It is a large-scale (Ⅱ) -type water control project that takes flood control, industrial and urban water supply as the mainstay, takes into account irrigation, combines power generation, breeding and tourism development at the same time. 2 Jiguanshan dangerous rock distribution and the dangers of the project Jiguan Mountain dam dam located in the right bank axis and diversion tunnel, spillway tunnel entrance and exit area, the body was a pagoda shape in the plane, connected by the three roots and the top of the mountain Each isolated high steep single thin bar mountain composition. Mountain three empty, by the river, deep river
