摘　　要：水上物探作为水下隧道勘察的主要手段,不同于地面物探,其技术要求高,施工难度大,单一物探方法很难取得好的勘探效果。在深茂铁路穿越珠江口隧道勘察中,采用了水上地震与浅层剖面相结合的综合勘探方法,两种方法优势互补,相互验证,综合解译,对水下隧道的隐伏构造、地质分层具有良好的勘探效果。应用结果表明:对于施工环境复杂的水下隧道勘探,采用综合物探技术,有利于提高勘探结果的准确性与可靠性,本文勘探方案对今后类似的水下隧道勘察具有借鉴性。As the main means of underwater tunnel exploration,the geophysical exploration on water is different from the surface geophysical exploration, which has high technical requirements and more difficulties in construction. Water seismic surveying combined with shallow acoustic surveying are used in tunnel exploration under the water of Shenzhen-Maoming railway project. These two kinds of exploration methods have complementary advantages and the geological information could be interpreted comprehensively to achieve a good exploration effect. Integrated geophysical technology is conducive to improve the accuracy and reliability of the detection results in underwater tunnel exploration. The application could be referred for the similar underwater tunnel exploration in the future.
