【Abstract】：In order to solve the problems of damage， low efficiency and high risk of traditional borehole exploration methods， the multi-channel transient surface wave method is applied to subway geotechnical exploration. By using this method to analyze and process the data collected in the target work area， the corresponding stratigraphic profiles are obtained. Compared with the borehole data， the application of multi-channel transient surface wave method to the geotechnical investigation of Subway has a better effect.

【Key words】：multi-channel transient surface wave technology; geotechnical investigation; subway

地铁修建前需要对城市环境下的岩土进行勘察，部分特殊环境对勘察手段要求较高，传统钻孔揭示勘察方法受到限制，需开发其他的勘察方法[1]。（剩余2415字）
