文档介绍：摘要
林江是我国大河流之一,其干流全长700公里,流域面积17400平方公里;楚河是林江的重要支流,流经林江的上下游地带,全长250公里,流域的面积为7200平方公里。楚河开发计划是配合林江而制定的。楚河楚林水利枢纽就建立在楚河和林江汇流处的楚林。
枢纽属一等工程,以防洪和发电为主,兼有航运等综合效益。其主要建筑物有:混凝土实心重力坝、引水建筑物、泄洪建筑物、放空建筑物、过坝建筑物和电站厂房等
枢纽按千年一遇洪水设计,五千年一遇洪水校核。,,。,总装机72000千瓦。船闸可以保证80吨级驳船通航。
,;泄洪采用表孔,共三孔,每孔宽12米,;放空采用深孔,设一孔,,高4米,底板高程151米;电站引水采用坝内压力钢管,;电站厂房为坝后式。
本设计对枢纽的主体建筑物进行了认真的方案比选和详细的尺寸设计,并对所设计的建筑物进行了安全校核,保证建筑物的安全运行。同时对水电站和施工导流进行了简要的设计。

Abstract
Linjiang River is one of the large stream flow in our country, which has 700 kilometers long, and drainage area covers about 174000 km2. Chuhe River, which is on the upstream of the Linjiang River, is the most important anabranch on the Linjiang River, it has 500 kilometers long and it’s drainage area covers 7200 km2. The development plan of Chuhe River is determined on the Linjiang River. The Chuhe Chulin water project plan is built at the Chulin, of which the accordant junction of Chuhe River and Linjiang River.
The Chuhe Chulin water project plan is the first class project, it’s main functions are flood control and power generation. The main building includes: the concrete gravity dam, the diversion head building, the emptying outlet building and water power plant etc.
Water project plan is designed according to meeting flood design once in millennium, and meet flood check once in five thousand years. The normal water level of the project is , the design flood level is , and the check flood level is total volume of the power generation units is 72000KW. The ship box can guarantee that 80 tons of barges get through.
This design pared several available projects earnestly and design detailed size. At the same time it checks the safety, and ensure the safe operation of the building. Simultaneously, the paper design the water power station and diversion work briefly.
