石湖水库坝址选择及坝型适宜性分析

摘要

石湖水库位于河北省涿鹿县西侧的桑干河主河道上,距县城26km,总库容5800万m3,属中型水库.根据现场勘察资料研究分析认为,有上下游相距1km的两个坝址供选择,对坝址区工程地质条件进行了分析,从地质角度给出了坝址选择的依据,并对坝型的适宜性进行了分析.%Shihu reservoir is located in the Sangganhe River trunk stream that lies the west of Hebei province Zhuolu county, it is about 26 kilometers from the Zhuolu city, the total capability is about 58 million m3,and it is a middle size reservoir. It bases on the locale investigations and the related data that selecting two dam sites. The distance between the two dam sites is one kilometer along the river. There are two projects that one is concrete overflow dam model and other is concrete-faced rockfill dam model. This paper analyzes the engineering geological conditions of the dam area , put forward the bases of dam sites selection at geological specialty, and analyze the adaptability of dam model too.
