摘要 隧道工程施工时,可能会受到爆破作业扰动、特殊水文地质条件等因素的影响而出现诸如冒顶、塌方、透水等突发事件,不仅影响施工活动的进行,还会对作业人员的生命安全造成危害[1]。花岗岩地区的山岭隧道富水地层出现塌方时,可采取WSS超前注浆加固、超前支护等措施,对塌方隧道掌子面上方及前方围岩产生固结作用,提高围岩自稳能力,可起到良好的处治效果。 During tunnel construction,unexpected events such as roof caving,collapse,and seepage may occur due to factors such as blasting disturbance and special hydrogeological conditions.This not only affects the progress of construction activities,but also poses a threat to the safety of workers.When collapse occurs in the rich water strata of mountain tunnels in granite areas,measures such as WSS advanced grouting reinforcement and advanced support can be taken to solidify the surrounding rock above and in front of the collapsed tunnel face,improve the self stabilization ability of the surrounding rock,and achieve good treatment effects.
