摘　　要：采用以孔压静力触探原位测试技术为主、钻探技术为辅的方法对港珠澳大桥海底地层进行了工程地质勘察。首先利用孔压静力触探技术进行了土类判别和力学分层,探知了软弱夹层的具体位置;然后结合钻探信息,验证了孔压静力触探技术勘察所得的地层信息的准确性。该研究可为港珠澳大桥的进一步设计提供有效且可靠的地质资料,同时本次海床式孔压静力触探技术的应用对工程地质勘察和原位测试技术的发展具有里程碑的意义。In order to get seabed strata information along the HZM bridge fast and effectively, this study completes the investigation by using CPTU technique and drilling technique. Also soil discrimination,mechanics stratification, the specific location of weak interlayer and drilling information are used to verify the accuracy of the CPTU information. All the work provides effective and reliable geological data for the further design of the bridge. The seabed CPTU technology application is a milestone in the development of engineering geological survey and in-situ test technology.
