摘要
在围岩完整性较好的高地应力地区及硬岩深埋长大隧道中采用钻爆法施工时易产生岩爆现象,从而对施工进度及人员安全造成威胁。本文结合在建的桃园至巴中高速公路米仓山隧道,针对施工中遇到的中-强岩爆危险以及工期紧张等难题,采用柔性防护网对裸洞洞壁主动防护作为隧道岩爆段施工时的支护,顺利通过岩爆段并加快施工进度,可为其他类似工程所借鉴。
It is easy to produce rockburst during the construction of drilling and blasting method in high geostress areas with good surrounding rock integrity and in the deep buried and long tunnel,it's a threat to the construction progress and personnel safety.This paper combines with Micangshan highway tunnel.In order to soive strong rockburst danger and tight schedule problem,using the flexible protective net of bare hole wall as the active protection of rockburst in tunnel.This not only can accelerate the construction progress,but also can be a reference to other similar projects.
