大风江调水工程东场挡潮闸闸室基础处理

Foundation treatment for Dongchang tide gate chamber of Dafengjiang water transmission project

介绍大风江调水工程东场挡潮闸工程的基础及工程地质情况,分析闸址底层岩性,提出了采用高喷防渗及换填粗砂的基础处理方法,实施结果表明:提高了挡潮闸闸室基础的地基承载力,且经济合理,效果较好。

Based on an introduction of the foundation and engineering geological conditions of the Dongchang the gate chamber of Dafengiiang water transmission project, the author analyzed the foundation rock properties, and put forward the foundation treatment measures such as preventing seepage with high-pressure sprayed concrete and replacement fill of coarse sand. The results of practice demonstrated that the foundation bearing capacity of tide gate chamber is improved with rational economic benefit and relatively good effect.
