海洋地球物理探测技术及其在近海工程中的应用

Marine Geophysical Survey Techniques and Their Applications to offshore Engineering

介绍了多波束测深、侧扫声纳测深、浅地层剖面测量、高分辨率地震测量和海洋磁力测量等五项海洋地球物理探测技术的最新进展和简单工作原理,给出了目前国内外广泛使用的主要技术产品型号以及主要参数和性能和展示了这些技术近年来在近海工程,例如海缆(海底光缆、电缆和管线等)路由调查、跨海大桥和海底隧道工程地质环境评价、工程灾害因素分析、海底目标物寻找和水下考古等方面的应用实例。

In this paper, the new advances in and simple principles of 5 marine geophysical survey techniques, including multibeam sounding, side scan sonar sounding, subbottom profiling, high-resolution seismic prospecting and marine magnetic survey are introduced, the main products widely used at home and abroad and their specifications are given, and some application cases of these techniques for offshore engineerings in recent years, such as submarine cable route survey, engineering geological environment evaluation of trans-sea bridge and submarine tunnel, analysis of engineering geological hazard factors, submarine object search and underwater archaeology are exhibited.
