摘要/Abstract

摘要： 经过对不同时期洪积物的成因、物质组成、结构、构造等的分析，以及对第一期洪积物内能否成洞的试验性模拟开挖、观察、分析，并在大量室内外物理力学性质试验的基础上，分析、量化出洪积物内成洞工程地质特性参数。在精心设计和施工下，深厚洪积物内开挖大跨度洞室顺利成功。

Abstract: Based on a large amount of laboratory and field experiments, and the excavation modeling experiment, through the analysis of the genesis, texture and structure of drifted material formed in different period, the engineering geologic conditions of forming hole in deep drified material are studied; and the physico-mechanaical parameters are achieved precisely. A wide span hole in deep drifted material has been successfully excavated at Xilongchi Pumped Storage Power Station. And the experimental excavation, observation and analysis are done to know whether the hole can be formed in the drifted material formed in the first period; and a lot of experiments in lab. and infield also are done. Finally, the physico-mechanical parameters of drifted material are achieved precisely. Through careful design and careful construction, it is successfal to dig big span hole in the deep drifted material.

Key words: drifted material, forming hole, engineering geology research, Xilongchi Pumped Storage Power Station
