Abstract: To understand the fracture structure on the impact of the project, collecting relevant in the study area, on the basis of geological and seismic data, through the field geology, structure (fracture) survey and geophysical work, check out the site of the building and its peripheral geological structure, the properties of foundation soil, coating thickness, distribution of active faults, etc.,SThe influence of fault structure on construction engineering site is evaluated to provide basis for site selection of construction projects within the evaluation area.
