摘要
探讨了高分辨率地震勘察技术在杭州湾萧山通道工程物探中的应用。围绕地震勘察方法的技术思路、陆域高分辨率地震勘察技术、水域高分辨率地震勘察技术、高分辨率地震勘察数据处理技术及地震勘察质量保证体系等几个方面,系统地介绍了高分辨率地震地球物理探测技术。通过陆域和水域,结合钻探资料成果,初步查明了杭州湾萧山通道盐官东方案桥位及其附近的地形、地貌特征,测定了第四系厚度、基岩面埋深、形态及第四系分层等,了解了桥位上断裂构造发育的位置、倾向、规模及其活动性,为工程可行性研究提供了可靠的物探依据。
The application of high-resolution seismic investigation technique in engineering geophysics of Xiaoshan Channel in Hangzhou Bay is investigated in this paper. Centering on the technical ideas of seismic investigation, the terrigenous high-resolution seismic investigation technique, waters high-resolution seismic investigation technique, high-resolution seismic investigation data processing technique, seismic investigation quality assurance system and so on, high-resolution seismic investigation technique is introduced systematically. Based on the drilling data result of terrigenous and waters, the bridge location of Yanguandong scheme and the topography geomorphology nearby are found out preliminary. The quaternary thickness, depth and morphology of bedrock surface and the quaternary dividing are determined. The location, tendency, scale and activity of fault structure at the bridge location are surveyed, and the geophysical prospecting basis for feasibility study is provided.
