摘要
Abstract
The river channel of Hanjiang River at Xinglong Hydro-junction site is wide. The main channel is on the middle-right part with low or high beach at both banks. 2-staged diversion was adopted in the construction of the project. Due to thicker overburden layer composed of fine sand with sandy loam, thick fine sand etc. , the foundation has low anti-scouring and strong permeability, so the anti - scouring and cofferdam seepage prevention are 2 key technical issues in diversion construction. Through the hydraulic and sediment tests as well as 2D seepage calculation, the principle of "preventing the point from souring and protecting the line" was adopted, so the anti-scouring problem was solved. The full cut plastic concrete cutoff wall was ap-plied for the transversal cofferdam and 2 longitudinal cofferdams with the layout form of full closed circular, which avoided the seepage stability failure. The problems occurred in the design and operation of the project and treatment measures are briefed to provide reference for other similar projects.关键词
