Abstract: Underground space development and utilization is an effective way to solve urban rickets. The precise detection of underground space under strong urban interference has become a hot topic in multidisciplinary research and also serves as the difficulty of current research. Taking Xi'an-Xianyang New District as the study area, the research on accurate detection and modeling of underground space has been carried out by using borehole exposure, experimental test, multi-parameter geophysical logging and ground geophysical exploration combined method. Multi-parameter geophysical characteristics of each layer of soil have been acquired through using integrated geophysical exploration. Based on the drilling exposure and experimental test data, the ground geophysical and logging calibration and coupling have been established based on drilling data, and then the physical properties have been assigned to the underground space geological structure model. It is proposed that high-density electrical method, micro-motion array observation and shallow seismic exploration combined with multi-parameter geophysical logging method can be used as the optimal combination method for underground space geophysical exploration under strong urban interference environment.
