摘　　要：针对渝黔高速公路重庆段崇溪河地区的地形地貌、工程地质条件和地球物理条件等特点,从工程实际应用出发,利用高分辨率的浅层地震法,即浅层地震反射法、折射法和面波法等地震勘探手段在崇溪河地区进行地震勘探工作;根据该地区多为山沟、河谷或悬崖、陡坡的地形地貌特征,简介了地震勘探测试原理和合理的测线布置;对上述几种浅层地震的测试方法所采集的相关信息进行了综合分析论证,查明该地区岩溶发育程度及空间分布情况,并得到了钻探的验证,为该路段的工程勘察、设计及施工提供了科学依据。According to the character of Chongxihe area Chongqing section of Yuqian freeway such as landform, engineering geologic condition, physical geography condition, considering the engineering application, a high definition shallow layer seismic method, namely shallow layer seismic reflection method, seismic refraction technique and surface wave machine, is used for seismic prospecting in Chongxihe area; because of the landform character in this area which is mostly the gully, river valley or cliff and steep slope, principle of seismic prospecting and rational layout of measuring line are introduced in brief, synthetic analytic demonstration is made about the correlative information which is collected by above seismic prospecting measurement ,then development and space distribution of carst are found out , finally it is validated by drilling that scientific warranty could be provided for investigation, design and construction of the section of this freeway.
