某水库大坝工程要件设计浅析

A Case Analysis of the Design of Principal Engineering Works of Reservoir Dam

为充分利用水资源,改善某县东南区域农业灌溉条件,兼顾防洪、养殖和生态用水需要,新建某水库,水库工程主要由大坝、溢洪道、输水洞、管理工程等组成。文章根据水库大坝工程水文地质,详述了坝顶工程、迎水坡、背水坡工程以及坝体及坝基防渗加固工程的设计方案。某水库工程的建设使水库下游农田灌溉得到保证,并提高下游河道防洪标准,枯水期为下游河道提高生态用水,为供水区域的粮食安全提供支撑,同时极大地改善了供水区域的生态环境。

In order to make full use of water resources,improve the agricultural irrigation conditions in the southeast of the county,and take into account flood control,breeding and ecological water demand,a reservoir will be built.The reservoir project is mainly composed of dam,spillway,water conveyance tunnel,and management facilities.Based on the hydrogeology condition of the reservoir dam project,the design scheme of dam crest,upstream slope and downstream slope,as well as the anti-seepage reinforcement of the dam body and dam foundation is described in detail.The construction of the reservoir project could provide sufficient water for farm irrigation in the downstream of the reservoir,improve the flood control standard of the downstream river channel,supplement the ecological water use of the downstream river during the dry season,provide support for the food security of the water supply area,and significantly improve the ecological environment of the water supply area.
