摘要
针对隧道洞口段浅埋偏压且围岩破碎的情况,提出地表注浆加固方法,通过在玉(林)铁(山港)铁路竹高岭隧道的施工实践,表明地表注浆对浅埋破碎围岩加固效果明显,现场可操作性强,值得推广。
According to the situation of tunnel hole entrance section shallow buried bias and broken surrounding rock, this paper put forward the surface grouting reinforcement method, through the construction practice of Yu-Tie railway Zhugaoling tunnel, showed that the surface grouting had obvious reinforcement effect of shallow buried broken surrounding rock, the site operability was strong, worthy of promotion.
