摘　　要：通过地质调绘、卫星遥感、物探、钻探及室内土工试验等多种勘察方法,对龙山隧道进行了综合地质勘察,查明了隧道工程地质、水文地质条件,基于岩石完整性和坚硬程度两个基本因素,对岩体基本质量指标进行了综合判定,并对围岩进行了分级,为隧道设计和施工提供了依据。The paper introduces the geological survey of Longshan tunnel through the methods of engineering geological mapping,satellite remote sensing,geophysical prospecting,drilling and laboratory soil test,etc. . Using such testing methods,the tunnel engineering geological and hydro-geological conditions are identified and evaluated. On the basis of the rock mass integrality and hardness degree of rock,the rock mass quality in-dex（BQ）was determined and the surrounding rock was classified,which provides a basis for the tunnel design and construction.
