摘要
水平岩层隧道围岩具有一定的松动圈特性,以在建某公路隧道为例,采用监测技术对水平层状围岩松动圈进行量测分析,并基于此提出锚固设计方案,经监控数据分析可知,其锚固效果是有效的,可为类似隧道工程设计与施工提供实践经验。
Surrounding rock of tunnel in horizontal rock stratum has characteristics of loosened rock circles. In this paper, taking a highway tunnel under construction as an example, using monitoring technology to measure and analyze loosened rock circles in horizontal rock stratum, the anchorage design plan is put forward. Through data analysis, it is found that the anchorage is effective, which provides practical experiences to similar tunnel engineering.
