摘要
堡镇隧道处于明显的软岩、高地应力地段,施工过程中左线正洞部分地段发生结构大变形。介绍了特殊复杂地质条件下,通过围岩监控量测配合系统支护,合理调整支护参数及施工方法,并在工艺上加以细化,归纳总结形成高地应力、软岩隧道综合施工技术。
Baozhen tunnel is in obvious soft rock,high ground stress area,there is a large structure deformation in part of left line hole in t construction process.This paper describes the special under complicated geological conditions,through the monitoring measurement of surrounding rock support system support,reasonable adjustment of support parameters and construction methods,and in the process to be detailed,summarizes the forming of high ground stress.
