1 概述孤石滩水库位于河南省叶县南34km的常村乡小呼沱村,属沙河支流澧河上游,始建于1958年,控制面积2.86万hm~2,总库容1.845亿m~3。是一座以防洪、灌溉为主,结合发电、养鱼等综合利用的大(2)型水库。为提高该库的防洪标准,1997年11月水库的除险加固工程开工。本文对该库加固工程的心墙土料和下游坝坡砾质土料进行了物理、力学性试验研究,以期为工程的建设提供可靠
1 Overview Bessatan Reservoir is located in Xiaotuo Tuo Village, Changcun Township, 34km south of Ye County, Henan Province. It belongs to the upper reaches of Bahe River, a tributary of the Shahe River. It was established in 1958 with a controlled area of 28,600 hm 2 and a total storage capacity of 184.5 million m 3 . Is a flood control, irrigation, combined with power generation, fish and other comprehensive utilization of large (2) reservoir. In order to improve the flood control standard of the reservoir, the reservoir reinforcement project started in November 1997. In this paper, the physical and mechanical properties of the core wall material and the downstream gravelly soil material of the reinforcement project of the reservoir are studied in a bid to provide a reliable basis for the construction of the project
