铜钱坝水利枢纽布置及重力坝设计
摘要
本设计通过对铜钱坝水库地质地形的了解及重力坝设计步骤的熟悉,对重力坝的各相关建筑物进行了具体设计。铜钱坝水库坝址位于汉江支流玉带河下游,,兼补偿下游农田灌溉用水3000万m3,以及防洪、发电、养鱼等综合利用水利枢纽工程,要求工业用水保证率97%,农田灌溉保正率75%。该工程属于Ⅲ等工程,主要建筑物为3级建筑物。
首先,在研究地质地形条件的基础上选择了最合适的坝轴线,并进行了枢纽布置。再经过调洪计算确定了设计、校核洪水位,在此基础上设计出了非溢流坝段基本剖面并进行了稳定验算、应力分析,结果均满足要求。泄水建筑物采用底孔表孔结合的形式,分别设计了溢流坝段和底孔坝段,消能形式采用挑流消能。最后,还对坝体的细部构造进行了设计。本次设计的主要成果有:设计说明书1份,设计图纸6张以及其他相关附图附表等。

Coins dam water conservancy project layout and design of gravity dam
Abstract
Through the design of the coins dam reservoir geological understanding and gravity dam design steps of the familiar, gravity dam on the various buildings of the specific design. Coins dam reservoir dam is located in the jade belt River tributary of the Hanjiang River, the reservoir is for a factory industrial water average downstream, pensation of farmland irrigation water30,000,000 m3, and flood control, power generation, pisciculture prehensive utilization of water conservancy project, requirements for industrial use of water for farmland irrigation guarantee rate97%, positive rate 75%. This project belongs to Ⅲ project, main building 3 buildings.
First, in the study of geological and topographical conditions based on the selection of the most suitable dam axis, and a pivot arrangement. After flood regulating calculation, design flood level, on the basis of the design of non overflow section of the basic profiles and the stability calculation, stress analysis, the results can meet the requirements of. The drainage building uses the bottom sheet bined forms, were designed and the bottom orifice spillway, energy dissipation forms using a ski-jump energy dissipation. Finally, also on the dam construction is designed. The design of the main results are: one design specifications, six design drawings and other related drawings schedule etc..
