Seismic reflection method is one of the commonly used techniques in urban underground space exploration. However, in some areas, the effect of reflection seismic exploration is limited because of the difficulty of interpretation. In this paper, seismic reflection exploration and refraction travel time tomography are jointly used in Hangzhou to increase detection accuracy. The results show that different layers can be discerned for Quaternary sedimentary. The combined use of the two methods has obvious advantages and good practical value.
