Abstract: As a result of the terrain and type of device,the method of ground high density resistivity cant reflect the geology accurately.This paper mainly introduces the working method of the well between resistivity CT.In view of the practical work,we carried out the numerical simulation test and forward-inversion calculation,and applied the method while detecting deep karst and the effect of the deep curtain grouting.We summarized the attention in the process of data acquisition and got the result and the drilling data for a comparative analysis and achieved a better result.
