随着海洋资源的开发与滨岸工程的建设,越来越多地遇到海洋地质灾害的影响与危害。为了避免并降低海洋地质灾害的影响程度,应开展海洋灾害地质与工程地质调查。二十多年来的实践经验表明,若采用以高分辨率地震为主,配合浅地层剖面、旁侧声纳、测深及磁力测量等综合浅层物探技术,对于了解海洋地质灾害因素与海底浅部工程地质特性等方面都能取得良好的效果,这是一种既经济又较快速地提供成果资料的好方法。

With the development of ocean resources exploration and shore engineering construction,we e-ncountered marine geological hazard.In order to avoid the damage,we should investigate ocean hazard geol-ogy and engineering geology.The practical experience in the past 20 years shows that shallow bed geophys-ical exploration techniques such as high resolution seismic investigation,seismic scan sonar,method of sounding,and magnetic observation can help us understand marine geology hazard and shallow bed engineering features economically and quickly.
