下溪水利枢纽引水隧洞围岩泥化夹层的工程特性

Engineering characteristic of the siltized intercalation of adjoining rock of water tunnel of Xiaxi Reservoir

泥化夹层是水利枢纽引水隧洞的主要工程地质问题之一,也是工程投资的敏感因素之一.结合江西省永丰县下溪水利枢纽引水隧洞的具体情况,对引水隧洞内泥化夹层物质组成、物理力学性质、成因及其工程特性进行了分析.

The siltized intercalation is the main engineering geological problem of water tunnel of Xiaxi Reservoir. It has an influene on project investment. Combined with the concrete condition of water tunnel,the composition,physical and mechanical feather, reason and engineering characteristic are analyzed.
