摘要
连接香港特别行政区、广东省珠海市、澳门特别行政区的港珠澳大桥,是一大型跨海通道,在大桥海中桥隧主体工程的补充地质勘察工作中采用了水域走航式高密度地震反射波勘探方法,取得了较好的勘察效果。本文结合实际工程,叙述了港珠澳大桥的地形地貌及地质概况,分析了该工程开展地球物理勘探的难点及对策,讨论了水域走航式高密度地震反射波勘探的具体实施方法和应用效果。
The Hongkong-Zhuhai-Macao Bridge, which connects the Hongkong Special Administrative Region, the Zhuhai city of Guangdong province and the Macao Special Administrative Region, is a large-scale thoroughfare over the strait. The method of high density seismic reflection wave was used in the supplement geological investigation for the bridge engineering by China Zhongtie Major Bridge Reconnaissance ＆ Design Institute Co., Ltd. which got the better geologic effect. The terrain and topographical features in the bridge area are introduced. The difficulties and the countermeasures for the physical geographical exploration in the project are analyzed, and the implementing scheme and effect for the method is discussed.
