摘要
新建贵阳—南宁客运专线贵州段站前工程GNZQ-6标段九万大山1号隧道为Ⅰ级风险隧道,地质条件极其复杂。文章采用物探和钻探、长距离探测和短距离探测相结合的探测方法,以及TSP地震波探测法、超前水平钻孔、加深炮孔的探测方法,准确预报出DK193+340~DK193+370断层的不良地质,为隧道的安全施工提供了重要保障。
The Jiuwandashan No.1 Tunnel in the section lot GNZQ-6 of Guizhou section of the new Guiyang Nanning passenger dedicated line is a class I risk tunnel with extremely complex geological conditions.This paper discusses the methods of geophysical probe and drilling,long-distance probe excavation and short-distance exploration,as well as seismic wave refl ection method,advanced horizontal drilling probe method and deep blast hole probe method are used to accurately predict the unfavorable geological conditions of DK193+340~DK193+370 fault,providing an important guarantee for the safe construction of the tunnel.
