摘要
针对山岭隧道开挖过程中地质探测的复杂性和局限性,结合桂林市某引水隧洞工程,综合利用高密度电法、大地电磁法、声波测井及剪切波速联合测试法对隧洞沿线地层岩性及不良地质体的分布与规模进行勘探。通过多种勘测结果,研究隧洞沿线的地层岩性及不良地质体的分布特征,并分析不良地质体对引水隧洞施工的影响,为隧洞安全施工提供坚实可靠的依据。
Addressing the complexities and limitations of geological exploration during mountain tunnel excavation,this study employed a comprehensive approach utilizing high-density electric methods,geomagnetic methods,sonic logging,and the shear wave velocity joint test method.The objective was to investigate the distribution and scale of stratigraphic lithology and undesirable geological bodies along the tunnel route,specifically in the context of water diversion tunnel project in Guilin.Through a variety of survey results,studying the stratigraphic lithology along the tunnel and the distribution characteristics of the undesirable geological bodies,and analyzing the impact of the undesirable geological bodies on the construction of water diversion tunnel,in order to provide a solid and reliable basis for the safe construction of the tunnel.
