摘要
本文对在软弱围岩条件下的隧道设计及施工技术特点进行了分析 ,涉及超前支护、开挖、二次支护、病害的治理等内容。通过山王庙大跨度隧道的施工 ,介绍了可供借鉴的一些施工技术及手段。
The designing and construction technique of tunnel under weaken surrounding rock conditions are studied herein,which deals with advancing bracing,excavation,the second bracing and prevention of hazard.Through the construction practice of long span tunnel at Shan Wang Miao in Yunnan province the construction technique is introduced for reference to similar project.
