Research on the application of fine detection technology of hidden structure in Zhengzhou City
The spatial of the buried tectonic framework is mainly detected by the combination of multiple methods,such as deep seismogenic environment analysis and shallow shallow layer location,to study the fault tectonic activity time in the target area.The deep space features are mainly explained by magnetotelluric sounding and deep reflection seismic inference,and the shallow space features are jointly explored by shallow magnetotel-luric and geological drilling.The stratigraphic age is determined by comprehensive analysis and research mainly through the formation lithology,sedimentary color and photoluminescence dating.Based on the exploration and evaluation of the activity in Zhengzhou,this paper explores the buried buried active fault by combining methods,reveals its precise spatial location and activity time,and determines that the structure is a buried fault in the early and middle Quaternary system,which provides a basis for the city to assess the risk and harm of active fault.It can be used as a reference for the detection of active faults in other urban hidden areas.
