汾河水库坝基防渗处理方案综述

Anti-Seepage Treatment Scheme of Dam Foundation in the Fenhe Reservoir

文中简要介绍了汾河水库的工程概况,重点研究了坝基渗漏问题,分别从左右副坝的风化岩石层和卵石混合土层入手,综合考虑地质、施工、投资等几个方面因素确定合适的坝基防渗方案,最终推荐风化岩石层采用帷幕灌浆,卵石混合土层采用高压喷射灌浆的方案。

The project profile of the Fenhe Reservoir was briefly introduced in this research. The dam foundation seepage was focused on for studying the weathered rock layer and gravel mixed layer located in left and right secondary dams. Reasonable anti-seepage scheme of the dam foundation was determined in the aspects of geology,construction and investment. The results show that the curtain grouting could be recommended for weathered rock layer,and the high pressure jet grouting could be recommended for gravel mixed layer.
