水域地震反射波法在岩土工程勘察中的应用

The Application of Marine Seismic Reflection to the Geotechnical Engineering Investigation

简要地介绍了水域地震反射法的基本工作方法、数据处理、解释技术及其在水域岩土工程勘察中的应用。通过该工程实践,基本探明了工区内的地层结构、基岩面起伏以及断裂分布情况,并形成多种成果图件。实践证明,水上高频、高密度多次覆盖的地震反射波法高效、经济、有效,地震反射波法几乎是水域物探方法的最优选择。

The paper briefly introduces basic working principle,data processing and interpretation technology of marine seismic reflection and its practical application to marine geotechnical engineering investigation.The result is satisfactory in the detection of strata structure,bedrock undulating and fault location,meanwhile,multiple charts are formed.It shows that CDP stack seismic reflection is high-productive,economic and effective.Marine seismic reflection is the preferred choice in marine geophysical prospecting.
