摘要
针对路河山隧道出口出现的塌方进行分析,从地表滑坡体和洞内施工两方面进行了论述,提出了先对地表滑坡体采用注浆小导管进行加固,再对隧道坍方段采用"先拱后墙法"进洞的处理方案,达到了安全进洞的效果。
Analysis the existing collapse in export of Luhe mountain tunnel, discussed from two aspects which are surface landslide and hole grouting, puts forward that first strengthens surface landslide using grouting mini tube, then using the method of wall after arch in tunnel collapsed section which reached the effect of safely into the hole.
