摘　　要：选取一种适用于城市环境工程地质勘察和软土地基的高技术含量、低成本的地球物理勘探方法是当今的趋势。为此首先介绍了一种采用人工叩板法激发横波,并用水平传感器取代垂直传感器接收横波反射信号,使横波取代纵波进行反射地震勘探的方法与原理。然后在塘沽进修学校和富力城南昌路进行横波地震反射实验,并对结果进行分析。通过所举的试验实例证明,浅层横波反射地震勘探能提供100m以浅真正意义上的浅层剖面,完全能符合工程上的要求。It is a trend to select a high technical content and low cost geophysical prospecting method which is suitable for the urban environmental engineering geological survey and the soft soil foundation. At first, this paper introduced the principle and seismic exploration method of shallow transverse wave reflection, by knocking the plate to excite the transverse wave signal, the horizon sensors are replaced by the vertical sensors to receive the transverse wave reflection signal, developing the reflection seismic exploration using transverse wave instead of longitudinal wave. Then the transverse wave seismic reflection tests are carried out in Tanggu school of training and education and on Nanchang road. The results are analyzed. According to the experimental examples in this paper, it proved that the shallow transverse wave reflection using seismic exploration method can provide a shallow section of 100 meters in a true sense, which can fully meet the requirement of the engineering.
