Application of Resistivity Composite Profile and High-Density Resistivity Method for Daiyuling Tunnel Engineering Detection

This paper is used by the combined test technology of resistivity composite profile and high-density resistivity method. Regard Daiyuling the first tunnel engineering geology survey work area as a test site. Different physical parameters such as resistivity composite profile curve of transverse sectionⅠ~Ⅳ line and vertical profile and measured, fitting apparent resistivity quasi section measured by high-density resistivity method reflect geological phenomenon. Through mutual contrast verification, improve the accuracy and reliability of survey results. Provide necessary geophysical basis for engineering geological exploration.
