摘　　要：跨海隧道的沿线工程地质条件对设计方案的影响较大,施工和运营中的一些风险也往往与地质条件有关。而通过钻探和物探相互印证,是查明隧道沿线工程地质条件的必要手段。物探工作可采用浅层地震反射法,以获取满足工程设计所需的地质资料。本文结合项目实际情况,介绍了项目中浅层地震反射法的实施过程,探讨了应用该方法探明海底隧道沿线工程地质条件效果。通过与钻探资料的比较,验证了应用浅层地震反射法探明海底隧道沿线地层的覆盖层厚度、基岩面变化情况等工程地质条件效果良好。The route＇s engineering geologic conditions of cross-sea tunnel can affect seriously the tunnel＇s design scheme. The risk in building and operation also is relevant to engineering geologic conditions. And it can find out the tunnel＇s engineering geologic conditions by means of mutual corroboration of geophysical prospecting and geological exploration. It can adopt the shallow seismic reflection method in geophysical prospecting. The paper introduces the method＇s implementation process of a cross-sea tunnel＇s survey project,and discusses the result. It is verified that it has good result in finding out the thickness of Quaternary overburden layer and the bedrock surface by using the shallow seismic reflection method.
