【摘    要】：為了解決傳統(tǒng)鉆孔勘察方法有損、效率低、風(fēng)險(xiǎn)高的問題，采用多道瞬態(tài)面波法對地鐵巖土進(jìn)行勘察，數(shù)據(jù)采集后開展分析處理，得到對應(yīng)的地層剖面；通過與鉆孔資料進(jìn)行對比分析，多道瞬態(tài)面波法應(yīng)用于地鐵巖土勘察的效果較好。

【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

地鐵修建前需要對城市環(huán)境下的巖土進(jìn)行勘察，部分特殊環(huán)境對勘察手段要求較高，傳統(tǒng)鉆孔揭示勘察方法受到限制，需開發(fā)其他的勘察方法[1]。（剩余2415字）
