我国水资源贮存量在世界上首屈一指。随着西电东送通道的建设以及西部经济的大开发,我国需要在西部大江大河上掀起新一轮水利水电工程建设的高潮,其中设施以发电站建设为主。以达到尽快改善我国的能源分配的不合理,满足社会主义现代化经济发展的需要。在水利设施不断新建的工程中,工程问题也在不断暴露,其中水库溢流坝溢流面钢筋混凝土水冲破坏是主要问题之一。为了保证水库可以安全可靠运行,水库滥流坝溢流面混凝土必须得到良好的设计和施工。本文结合一个具体实例对水库滥流坝溢流面混凝土水冲破坏原因进行简要的分析,对溢流面改造原则、措施进行了阐述。
China’s water storage is second to none in the world. With the construction of the west-to-east power transmission channel and the development of the western economy, China needs to set off a new round of climactic construction of water conservancy and hydropower projects on the major rivers in the west of China. The facilities are mainly power station construction. In order to achieve as soon as possible to improve our country’s energy distribution unreasonable to meet the needs of the socialist modernization and economic development. In the continuous construction of new water conservancy projects, engineering problems are also constantly exposed, of which overflow overflow spillway reinforced concrete water erosion is one of the major problems. In order to ensure the safe and reliable operation of the reservoir, the overflow surface concrete of the overflow dam should be well designed and constructed. In this paper, a concrete example is given to analyze the causes of water erosion of concrete overflow surface of reservoir overflow dam and to explain the principles and measures of overflow surface reconstruction.
