摘要
深埋长大隧道在施工中经常出现难以预料的不良地质体,给施工带来安全隐患。结合梅花山隧道工程,采用HSP水平声波剖面法对施工掌子面前方围岩进行超前地质预报,并提出了相应的对策措施,取得了较好的应用效果。
Construction of deep-embedded long tunnel often meets unexpected unfavorable geological bodies,bringing potential safety hazard.Combining with the Meihuashan Tunnel engineering,horizontal sonic profile(HSP)method is used to carry out geological forecast in connection with the surrounding rock in front of the tunnel face in the course of construction,and corresponded countermeasures are proposed to get good effect.
