摘 要
水闸是一种利用闸门挡水和泄水的低水头水工建筑物，多用于河道,渠系及水库、湖泊岸边。
根据教学安排，在学完全部课程之后，学生要进行综合性毕业设计，以进一步巩固所学知识。通过毕业设计提高学生解决工程实际问题的能力。初步掌握水利枢纽工程设计过程的整个思路。通过设计资料分析，编写设计文件，进行各种计算和绘制图纸，提高学生独立思考，钻研问题的能力。本设计包括以下内容：
一、 设计基本情况、水文气象情况、工程地质和交通运输条件的概述； 二、 闸孔、消力池、海漫、防冲槽等的设计；
三、 泄洪闸防渗排水设计，其中包括地下轮廓线布置和渗流计算； 四、 对闸室结构的布置和闸室分缝及止水设备； 五、 上、下连接物的作用及布置情况；
六、 闸室稳定计算，包括完建无水期荷载计算和设计洪水位时荷载及验算； 七、 闸底板内力计算、配筋情况计算；
八、 挡土墙设计情况，边墙设计和翼墙设计情况 九、 对设计进行总结。

He Jun Ying
(Water conservancy and Cvil engineering college, South China Aricultural Uiversity ,Guangzhou,510642, China.) Abstract:
Water is a kind of using water and discharge water retaining sluice gate of hydraulic structures and lower head for river, lake, reservoir and the canal.
Teaching arrangements, after the school complete the department of courses the students to conduct a comprehensive school design, in order to further consolidate the knowledge. Graduation project to improve the ability of students to solve practical engineering problems. Initial grasp of the whole idea of the water control project design process. Through the design of date analysis, preparation of design documents, the ability of a variety of calculations and drawings, to improve students’ independent thinking, and study the problem.This design includes the following:
1、Design,hydro-meteorology conditions,an overview of engineering geoglogy and transport conditions;
2、The gate hole,plunge pool,apron,anti-notching and other design;
3、Suice imearmeable drainage design, including the underground contour arrangement and seepage calculations;
4、The layout and the lock chamber of the lock chamber structure parting and sealing devices;
5、On the role to connect and layout;
6、The chamber of the stability calculation, including the finished built anhydrous load calculation and design of flood loads and checking;
7、Sluice bottom , force calculation , calculation of reinforcement and pier structures; 8、Retaining wall design , wall design and wing wall design situation; 9、Summarize the design.
.Key words：Sluice Graduation Dsign Load Calculation Structure Checking
