摘要
随着公路交通网越来越密集,设计线路不可避免地要穿越岩溶区,尤其是山区高速公路,还会出现隧道穿越岩溶区的现象。贵州省三凯高速公路SK13隧道对岩溶区采用超前注浆、格栅拱架加强的处理工艺,取得良好的工程效果。对注浆设计、施工工艺、工程质量检验等方面进行总结,对类似的采空区治理工程有一定的参考作用。
As the destiny of road growing higher and higher,it would be unavoidable to encounter karst cave area when designing a road,especially in mountain district,a freeway with tunnel through karst cave area is although seen sometimes.SK13 tunnel in Gui Zhou San-Kai Freeway which is through karst cave area is constructed successfully by treatment of pre-grouting and advanced bolt and steel grids in those poor condition area.The paper summaries the experiences of design of pre-grouting,construction technology,quality inspection,et al.,which could be a reference for similar project.
