长江马鞍山河段小黄洲左汊口门区河势控制工程设计

Key Technology Design of River Control Project for Xiaohuangzhou Left Branch Gate Area of Maanshan Reach of Yangtze River

文章针对长江马鞍山河段整体河势情况及小黄洲左汊分流比持续增加等问题,对长江马鞍山河段河势控制工程即小黄洲左汊口门护底工程进行方案比选及关键技术设计,并通过护底工程稳定性分析计算,验证所选方案的安全可靠性。

In this paper,the author,be aiming at the problems that the river levels vary more in Maanshan reach of Yangtze River,and diversion ratio of the left branch of Xiaohuangzhou continue to increase,compared and selected the schemes of bottom protection project at the entrance of the left branch of Xiaohuangzhou,and designed the key technology,also through the analysis and calculation for bottom protection project stability,determined the safety and reliability for the selected scheme.
