Abstract In this paper, a submarine tunnel in Xiamen is selected as the target area. Using electromagnetic bubble source system seismic wave excitation and the seismic imaging test of igneous rocks, we better identify the water depth of the sea mud (sand) interface, and the bedrock surface boundary. Under the geological background of granite weathering in the igneous rock development area, the bedrock surface has been greatly undulating, and the single drilling method has great limitations. The results show that the seismic image method is an effective geophysical prospecting method for igneous rocks in marine areas, and can provide a reliable geological reference for marine geological exploration. The use of water seismic imaging exploration not only can better compensate for drilling defects, but may also greatly save economic costs. Further, it has higher application value and scientific research value.
