【摘要】：水闸作为调节水位、控制流量的水工建筑物,具有挡水和泄(引)水的双重功能,起着防洪排涝(挡潮)、灌溉供水、水资源调控、改善水环境等作用,是减少自然灾害损失、保障经济社会发展和人民群众生命财产安全的重要基础设施,是我国水利工程体系的重要组成部分。截至目前,全国共有大中型水闸7000多座,大部分建于20世纪50~70年代,限于当时经济技术条件,建设标准低、施工质量差,加之长久运行,部分水闸老化失修严重,影响防洪、排涝、挡潮、引水等功能的正常发挥,亟需进行除险加固。本文选取江西省潦河灌区解放闸坝为例进行水闸的加固方案研究与设计。主要包括以下四个方面内容:1、通过对水闸现场检查及水力结构复核计算,分析总结解放闸坝存在的问题;2、针对解放闸坝存在的问题,研究解放闸坝的不同加固方案的可行性,并确定加固方案;3、针对方案进行加固设计;4、分析加固效果和投资情况,总结加固效果效益和经验。
[Abstract]:As a hydraulic structure that regulates the water level and controls the discharge, the sluice has the dual functions of retaining water and draining (drainage), which plays the role of flood prevention and drainage, irrigation water supply, water resources control, improvement of water environment, and so on, which is to reduce the loss of natural disasters. The important infrastructure to guarantee the economic and social development and the safety of the people's life and property is an important part of the water conservancy engineering system in China. Up to now, there are more than 7000 large and medium-sized sluices in the country, most of which were built in the 1950s and 1970s. Limited to the economic and technological conditions at that time, the construction standards were low, the construction quality was poor, coupled with the long-term operation, some sluices were aging and disrepair seriously, which affected flood control. Drainage, tide, water diversion and other functions of the normal play, need to be strengthened. This paper selects the Jiefang dam in Liaohe Irrigation District of Jiangxi Province as an example to study and design the reinforcement scheme of sluice. Mainly includes the following four aspects: 1, through the field inspection of sluice and the hydraulic structure review calculation, analyzes and summarizes the problems existing in the liberation gate dam. In view of the existing problems of the liberation gate dam, the feasibility of different reinforcement schemes of the liberation gate dam is studied. The reinforcement scheme is determined and the reinforcement design is made for the scheme. The reinforcement effect and investment are analyzed, and the benefit and experience of the reinforcement effect are summarized.
