浅谈山岭隧道工程地质勘察

A Brief Talk on Engineering Geologic Investigation of Mountain Tunnel

山岭隧道工程地质勘察是根据公路基本建设程序的不同阶段对地质资料的深度要求分阶段进行,一般采用资料收集与研究、工程地质调绘、钻探、物探及各种测试试验等综合勘察方法、手段进行勘察,其最终目的是详细查明隧址区的地质条件,确定隧道围岩级别,为隧道施工布置、各段洞身掘进方法及程序、支护及衬砌类型或整治工程设计提供详实可靠的工程地质依据。

According to the depth demand of different stages ofhighway＇s basic construction procedures,the engineering geologic conditions of mountain tunnel should be investigated by different stages, and usually the comprehensive investigation methods would be used,such as material collection and study, engineering geological mapping,engineering geological drilling, geophysical exploration and testes of all sorts,ect.The final aim is to find out the engineering geologic conditions of mountain tunnel,confirm the classification of surrounding rocks, provide the full and accurate engineering geologic basis for the design and construction of mountain tunnel, including the construction layout, the ways and procedures of excavation construction, the supporting and lining types and the regulation engineering design.
