摘　　要：以往由于近地表工程地震横波勘探的激发、接收在技术上的复杂性、识别困难，以及勘探深度（70～100m）有限所致，故对地震横波的利用比较少．通过总结多年工程探测实践的经验，提出了用地震横波反射法可以高精度地解释地下含水洞穴等灾害性地质体产状和形态，这是一种行之有效的实用方法和解释技术．锤击震源探测深度一般可达到200～300m，且规律、特征明显．探测成果多次经过开挖和钻孔验证，证明方法可靠，可作为主要手段为今后城市灾害地质调查、矿山采空区和工程场地评价检测提供相关信息和依据．Because of the technical complexity of excitation and reception and difficulty in wave recognition especially the limitation of exploring depth （70- 100 m） in seismic transverse wave reflection method for shallow-layer projects, the transverse wave method was rarely used. However, based on practical experience for years, the seismic transverse wave reflection method was found able to interpret practically and effectively such catastrophic geological structures as underground water-bearing caves with high precision, of which the exploring depth for seismic focus by hammering can be up to 200 - 300 m in general, thus providing evidently their formation and features. Through digging and drilling for many times, the exploring method was proved reliable and provide relevant information for urban disaster investigation and evaluation of gob areas and construction sites.
