摘要
In order to verify the correctness and applicability of the conclusions, two field tests have been carried out in Qingdao Jiao Zhou sub sea tunnel. TSP method was used to detect the seafloor in the field tests of sub sea tunnel, and the results verify the special laws of seismic wave reflection. According to the field tests conclusions and engineering examples, seismic wave reflection laws of large-scale underground water-bearing body have been summarized.
