摘　　要：介绍了采用地震映像法和高密度电法对广州市白云区某场地地下土洞和溶洞情况进行物探勘查。勘查结果揭示了场地内溶洞、土洞的发育情况、分布规律及充填物,以及上部岩层的厚度情况。与钻探资料对比表明,物探推断与钻探资料较吻合,地质效果良好。综合勘查方法揭示了对类似场地的岩溶探测问题的有效解决方案。This paper introduces the geophysical exploration of underground soil and karst caves in a site in Baiyun District,Guangzhou by using seismic mapping method and high-density electrical method.The exploration results reveal the development,distribution and filling of karst caves and soil caves in the site,as well as the thickness of the upper rock layer.The comparison with the drilling data shows that the geophysical inference is in good agreement with the drilling data and the geological effect is good.The comprehensive survey method reveals an effective solution to the karst detection problem of similar sites.
