要
本次毕业设计的题目是江西省峡江水利枢纽工程可行性研究。 峡江水利枢纽位于江西省峡江县境内的赣江， 工程以防洪发电为主。 水库总库容 11.87 亿 m3，装机容量 9 40MW，重力坝按Ⅰ级水工建筑物设计，厂房（非挡水）按 2 级水工建 筑物设计，次要建筑物 3 级。 峡江水利枢纽由重力坝，厂房，船闸三部分组成。设计者通过抗剪断公式和材料力学 法分别按设计洪水位情况和校核洪水位情况计算建筑物的稳定情况。 由于有交通要求，故除了检修桥之外，整个枢纽的上游侧还设置有交通桥，以满足交 通需要。 设计者采用的泄水建筑物为无坎宽顶堰。 设计者采用的厂房形式为河床式厂房，水轮机形式为灯泡贯流式。

前言
峡江水利枢纽工程位于赣江中游峡江县老县城（巴邱镇）上游峡谷河段，距峡江 老县城巴邱镇约 6 ㎞，控制流域面积约 62900km2 ，是一座以防洪、发电、航运，兼 有灌溉、供水等综合利用功能的水利枢纽工程。 工程建成后，可将南昌市防洪标准从 100 年一遇提高到 200 年一遇，使赣东大堤 的防洪标准从 50 年一遇提高到 100 年一遇。工程位置优越，效益大，工程量相对较 小，但淹没损失大。库区宜采取防迁结合方式，妥善解决移民安置问题，可以减少库 区淹没损失。 该工程是赣江干流中游河段综合效益较为显著的骨干工程， 是江西省 “十 五”水利建设首要工程。

Abstract
The topic of this graduation design is a feasibility study about complex engineer in Jiangxi Province. Xiajiang hydraulic complex is located on Ganjiang River in Xiajiang county, Jiangxi Province,whose main function is flood prevention.The other being power generation .The reservoir has a total capacity of 1187 million cube meter, and the hydropower capacity of 9 40 MW. The Gravity dam is desinged accord to a rank Ⅰhydraulic building. The Power station is desinged at a rank 2 hydraulic building and subordinate buildings are ranked Ⅲ. Xiajiang hydraulic complex is composed by three parts: the Gravity dam, the facility built on a river section with a large drop and power generation buildings at the right bank. The designer calculates stresses of certain points of the gravity dam by the shear strength formula and material mechanics , respectively at the load combination of the design flood level and the water level of check flood. Owing to there is several demands of transportations, so in addition to the examine and repair of the bridge, the lock chamber of the upstream side of the bridge traffic is also set to meet the transport needs of. The designer chooses the short weir . The designer chooses the water power generation programme the Xiajiang hydraulic
