百色水利枢纽导流隧洞工程地质分析及开挖支护措施

摘要

为查明百色水利枢纽导流隧洞主要工程地质问题，采用多种手段进行工程地质勘察，分析评价工程地质条件，提出开挖支护措施。并总结了该导流隧洞工程地质勘察及施工地质主要技术特点。%In order to identify the major engineering geological conditions for the diversion tunnel of Baise Multipur-pose Dam Project, multiple methods had been adopted for engineering geological investigation;The author analyzed and evaluated the engineering geological conditions;discussed the key geological problems;put forward excavation support measures;and summarized major technical characteristics of geological investigation and construction.
