    Abstract
  • The underground hidden karst developed in the limestone area has brought great safety hazards to urban engineering construction. Conventional geophysical prospecting methods are difficult to meet the high-precision detection requirements of urban engineering for karst diseases. This research introduced a cross-hole elastic wave CT technology, which can perform high-precision imaging of the underground structure of the engineering site. In combination with other geological data of the site, the shape and scale of the karst in the site area can be accurately predicted. The technology was applied in project practice, and the results show that the elastic wave CT method has achieved accurate identification of underground hidden karst, which is consistent with the geological drilling data.
