武穴水道航道整治工程坝体新结构研究

本文结合长江中游武穴水道航道整治工程的工程需要,分析了航道整治工程传统坝体结构的优缺点和破坏原因,根据武穴水道的工程条件,设计出了适合长江中下游航道整治工程的新型坝体结构型式——箱体坝和沙枕-模袋混凝土盖面坝体,并进行了成功的运用,结合运用后的效果对新型坝体结构的前景进行了预测。

New dam structure in Wuxue waterway regulation project

Considering the requirements of the Wuxue waterway regulation project, which is carried out in the middle reaches of the Yangtze River, this paper presents an investigation of the advantages, disadvantages and destruction reasons of the traditional dam structure in channel regulation projects. Furthermore, according to the Wuxue waterway conditions, new dam body structural types, i.e. box dam and sand pillow bag-concrete covered dam are proposed and applied successfully in the project. The prospects of the new dam body structure are forecasted based on the application effects of the new dams.
