摘要
针对武广客运专线大瑶山隧道发生的涌水现象,通过采用地质调查确定了岩溶发育情况,根据地质综合分析了涌水机理和危害,采用以全断面超前帷幕注浆堵水、周边超前大管棚支护为主,开挖后径向注浆为辅的隧道涌水限排控制技术,有效的控制了地下水的流失,获得了良好的效果。
In light of surging water phenomenon occurring in Dayaoshan tunnel on Wu-Guang passenger special line, through geological survey, it determines karst development situation, comprehensively analyzes surging water mechanism and hazards according to comprehensive geological analysis, adopts advanced curtain grouting for whole section and advanced peripheral bassoon and tents supporting as the points, takes vertical grouting tunnel surging water drainage limiting control technique as the subordinated way, it effectively controls the underground water loss, and achieves good achievements.
