摘要: 为满足渤海海峡跨海通道地壳稳定性调查评价项目的调查要求,在渤海海峡海域进行了小道距高分辨率多道地震探测。外业采集系统主要由电火花震源、24道数字固体缆及采集系统组成,通过外业系统的试验、数据采集和外业质量监控,获得了高分辨率的地震数据,分辨率可达2.5 m。结果证明,本次使用的24道高分辨率多道地震测量技术是一种适用于海域浅部地层调查和构造调查的有效的调查技术方法手段,可广泛应用于浅海工程高分辨率勘测。

Abstract: The small group interval high-resolution multi-channel seismic survey has been used for the crustal stability assessment of the cross-sea path of the Bohai Strait. Field acquisition system is mainly composed of electric sparks, 24 digital solid lines and acquisition systems. Trough field testing of the system, data collection and quality control, the resolution can reach 2.5 m. The results of this study show that the small group interval high-resolution multi-channel seismic system survey is an effective mean to shallow marine engineering, environmental and sedimentological researches.
