A comprehensive crosshole tomography method for karst identification based on color fusion technology
Single crosshole tomography features a multiplicity of solutions,rendering it challenging to accurately identify karst anoma-lies.Given this,this study introduced color fusion technology and tested its effectiveness in the inversion of three types of crosshole seismic CT data using numerical simulations:elastic wave travel time CT,elastic wave attenuation CT,and electromagnetic wave atten-uation CT.A field experiment on karst identification using comprehensive crosshole CT data reveals that the color fusion technology can effectively enhance the accuracy of karst identification.The results of this study provide an effective method for comprehensive crosshole detection and interpretation for karst exploration in foundational projects such as oil and gas pipelines,bridges,and tunnels,holding great significance for improving the exploration accuracy of karst.
