浅海工程中小道距高分辨率多道地震方法的应用
|
摘要
小道距多道地震排列是一种高分辨率的探测方法,利用该方法在鲁家峙-西闪岛-登步岛浅海连岛工程中获取高精度的地震数据,通过对数据进行分析处理与解释,获得调查区域的工程地质属性,了解基岩埋深和断层分布等情况,为编制预可行性研究报告提供必要工程地质依据。结果表明,小道距多道地震可以成功地应用于浅海工程环境地质调查。
Small group interval high-resolution multi-channel seismic system surveys have been used for the shallow marine bridge project at Lujiashi-Xishan island-Dengbu. Engineering geological condition of this area has been acquired through the processing and interpreting of seismic data. Discovering the engineering geological properties and the fault distribution, which is the necessary geological basis for the preparation of pre-feasibility of bridge site and route. The results of this study show that small group interval high-resolution multi-channel seismic system survey may be an effective way to the shallow marine engineering and environmental applications and sedimentary research.
