APPLICATION OF SMALL GROUP INTERVAL 24-CHANNEL HIGH-RESOLUTION SEISMIC TO THE PROJECT ON BOHAI CROSS STRAIT PATH

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.
