摘要
S水电站坐落于D江流域，属于河床式电站。电站采用混凝土重力坝挡水，混凝土溢流坝泄洪。厂房布置在河床左岸，船闸位于右岸，溢流坝段位于河床中间。水库设计洪水位90m（百年一遇），相应的下泄流量20500m3/s；（千年一遇），相应的下泄流量22500m3/s； m。本次主要设计混凝土宽缝重力坝。首先进行基本剖面设计，确定坝顶高程，然后确定坝顶宽度，然后根据不同坡率设计三种方案，三种方案在满足稳定应力前题下，择优选择用量比较省的方案，然后在进行实用剖面的各种荷载计算，进行稳定分析和应力分析。稳定分析和应力分析这里主要分四个截面进行分析，分别是上下游折坡点，坝基面以及宽缝部位。然后进行边缘应力分析和局部应力分析，最后进行挡水坝段的设计。
关键词 混凝土宽缝重力坝；剖面设计;荷载计算;稳定分析;应力分析。

Abstract
S hydropower station is located in D river basin, belongs to the riverbed power station. Power station adopts the concrete gravity dam in water, concrete computation. Building layout in the river left bank, lock is located on the right bank, computation in the middle river. Reservoir design flood level of 90 m (better), and the corresponding analyzed 20500 m3 / s; Check flood level of m (millennium), the corresponding analyzed 22500 m3 / s; Design level of 87 m. design low water level of 84 m. The main design joint of concrete gravity dam. First basic profile design, to determine crest elevation, and then determine the width of dam crest, and then according to the different rate of slope design three kinds of solution, three kinds of solutions to meet stability under stress before problem, dosage of merit-bas
