摘要

The tunnel is a structure built underground, and its excavation process often encounters complex geological conditions such as fault fracture zones and water-bearing areas. Based on the different response of different geological prediction methods to geological bodies and their influence on construction, more than two geological prediction methods are used to ensure construction safety. In this paper, TSP method and transient electromagnetic method are used to complement each other in the advanced prediction of tunnel. According to the previous survey data, we have a certain understanding of the development of rock mass. The fault fracture zone and water-bearing area are detected by TSP method and transient electromagnetic method. Through the corresponding software of the system, the three-dimensional visualization images of the fault fracture zone and the water-bearing area by TSP method and transient electromagnetic method are realized, the extension range of the fault fracture zone and the water-bearing area is defined, and the spatial distribution is described in detail. Based on the background of Huize Tunnel in Yunnan Province, the TSP method and the transient electromagnetic results are three-dimensionalized, and the information of the fault fracture zone and the bad geological body such as water content in the K1 + 935 ~ K1 + 855 section of Huize Tunnel is obtained.
