摘 要
本设计课题为玉环市礁门塘出险加固工程水闸扩建设计，其主要作用为挡潮、泄洪、冲淤等功能。由闸室及上下游连接段三部分组成。闸室段包括底板、闸墩、岸墙、闸门和工作桥等部分组成。上游连接段包括上游护坡、上游翼墙及铺盖等组成。下游连接段由下游翼墙、消力池和防冲槽等组成。设计任务为根据《礁门塘安全评价报告》结合台风期工程运行状况确定礁门塘闸门存在安全隐患，需进行礁门闸进行除险加固。要求我们将大学期间所学的课本知识实用化系统化并加深巩固，通过此次设计我将掌握闸门的总体布置、水力计算、荷载计算、渗流分析和稳定性分析。学会水闸的结构设计，熟练掌握CAD绘图技能。
关键词：水力计算，渗流分析，稳定性分析
Abstract
This design subject is the expansion design of the sluice of the reinforcement project of Yuhuan reef gate pond. Its main functions are tide blocking, flood discharging, silting and so on. It is composed of gate chamber and upstream and downstream connection section. The gate chamber section consists of base plate, gate pier, bank wall, gate and working bridge. The upstream connection section consists of upstream revetment, upstream wing wall and blanket. The downstream connection section is composed of downstream wing wall, stilling basin and anti scour groove. The design task is to determine the potential safety hazards of the reef gate according to the "reef gate pond safety evaluation report" and the operation condition of the project in the typhoon period, and the reef gate gate shall be reinforced. We are required to systematize and consolidate the textbook knowledge learned during the University. Through this design, I will master the general layout, hydraulic calculation, load calculation, seepage analysis and stability analysis of the gate. Learn structural design of sluice and master CAD drawing skills.
Key Words：Hydraulic calculation, seepage analysis and stability analysis
