武广客专大断面软弱破碎围岩隧道开挖及支护

摘要

This paper analyzed the excavation methods and supporting measure of large cross section soft and fractured surrounding rock tunnel of Wuhan-Guangzhou passenger dedicated lines, discussed the rapid excavation and support technology of low level surrounding rock tunnel suitable for large section different geological conditions, pointed out the large cross section passenger dedicated tunnel excavation methods selection should combined with specific geological conditions, construction technology and spot management level.%就武广客专大断面软弱或破碎围岩隧道的开挖方法和支护措施进行了分析，探讨了适用于大断面不同地质情况低级别围岩隧道的快速开挖和支护技术，指出大断面客专隧道选择开挖方法时应结合具体地质条件，施工技术和现场管理水平决定。
