摘　　要：针对中马友谊大桥所处珊瑚礁灰岩区,存在欠缺礁灰岩的工程分类参考资料问题,单一勘探方法很难取得好的勘察效果。结合勘察实例,采用侧扫声纳、浅层地震反射和地震映像相结合的综合物探技术,配合地质钻探,多种方法优势互补,互相印证,综合解译,对桥位区地质分层、基岩变化情况和海底障碍物探测取得了良好的勘探效果。应用结果表明:对于复杂多变的海底勘探,充分发挥物探探测的优势,可快速准确达到探测目的,将现在以勘探点为主的勘察模式,发展到点、线、面相结合的水平,大大提高了勘察成果的准确性和可靠性,本文勘察方案可为今后同类工程的勘察提供技术借鉴。The Sinamale Bridge is built in the coral-reef limestone area.The experience of engineering soil classification is not enough,so the single method to investigate the site couldn’t get the good results.Combining the investigation example,the side-scan sonar,the shallow seismic reflection and the seismic imaging method combined with the drilling methods are used in this project.These methods verify each other by using their advantages and achieve the good results to find out the stratum,depth of base rock and obstacle.For the complex and changeable underwater geotechnical investigation,the advantages of geophysical prospecting can be brought into full play,and the purpose of exploration can be achieved quickly and accurately.The present exploration mode,which mainly focuses on exploration points,will be developed to the level of combining the point,line and surface,which is greatly improving the accuracy and reliability of the investigation results.This way to combine the utilization of multi engineering geophysic methods could provide a good reference for similar projects in the future.
