Taking Fengdu-Shizhu, Chongqing highway tunnel engineering synthetic geophysical investigation as an example, and using synthetic shallow earthquake geophysical method and transient electromagnetic wave method (TEM), we realized the investigation objective of highway tunnel that bedrock depth, fluctuation situation and harm geological structure, and solve the problems of fast testing, data analysis and judgment method in highway tunnel engineering geological exploration. Shallow earthquake method using SE2404EX multifunctional digital seismograph and transient electromagnetic method using PROTEM EM-67 transient electromagnetic from Canadian GEONICS company were introduced in this paper, such as the working principle, equipment, working method, seismic line arrangement, data processing flow, data interpretation, and result analysis, etc.
