水域高密度地震映像法在舟山大陆连岛工程中的应用

本文介绍了水域高密度地震映像法的原理及震源、定位、数据采集和处理等技术特点,并以舟山大陆连岛工程勘察为例,说明如何根据地质地球物理条件和方法特点选择合适的工作方法与技术参数,阐述了水域高密度地震映像法在调查海底地形、覆盖层厚度、地层岩性特征及地质构造的位置、规模、产状等工程地质条件中的应用。

Application of estuary high density seismic imaging to the island-mainland link project in Zhoushan

The principle of estuary high density seismic imaging and the technological characters of seismic source, position, data acquisition and processing are introduced. Taking the engineering exploration of the island-mainland link project in Zhoushan as an example, it is explained how to select suitable methods and parameters according to geological and geophysical characters. The applications of prospecting the undersea topography, thickness of capping layer and lithologic characters, and the position, scale and occurrence of geological structure are expatiated by using estuary high density seismic imaging.
