大断面隧道地质勘察方法应用及成果分析——以黑白面将军山隧道工程为例

The Application and Result Analysis of Geological Survey Method for Large Cross-section Tunnel——Taking the Black and White Jiangjunshan Tunnel Project as an Example

地质条件复杂的大断面隧道地质勘察和围岩分级一直是市政勘察工作的重点,文章以黑白面将军山隧道为例,运用多种地质勘察手段后,通过对各种方法分析利用、相互验证、相互比较、综合判定,最终查明了隧道的工程地质条件,并对地质成果进行了分析,对围岩分级进行了修正,预测可能产生施工地质灾害的破碎带、突涌水位置,经施工开挖情况与实际相符。

The geological survey and surrounding rock classification of large cross-section tunnel with complex geological conditions have always been the focus of municipal survey work.Taking the black and white Jiangjunshan tunnel as an example,after using a variety of geological survey methods,through the analysis and utilization of various methods,mutual verification,mutual comparison and comprehensive judgment,the engineering geological conditions of the tunnel are finally identified,the geological results are analyzed,and the classification of surrounding rock is revised.The fracture zone and water inrush location predicted that may cause construction geological disasters is consistent with the actual situation after construction excavation.
