摘要
软弱土质隧道围岩自稳性差,易产生塌方,根据这一特性,选择了沙合拉峁隧道的进口段软弱围岩段,进行了水平钻孔旋喷机试验及加固技术研究取得了一定的经验。
The study on horizontal rotating and injecting pile and its reinforcement technology has been conducted in the entrance section of Shahalamao Tunnel due to the poor self - standing ability and the easily collapsed characteristics of the soft surrounding rock, from which some experience is gained.
