摘　　要：为了验证高密度电阻率法、地震映像法在岩溶勘查中的应用效果,对比两种方法在岩溶等不良地质现象勘探中的应用,分析总结岩溶视电阻率断面异常特征及地震映像图像特征。以桂林冶金厂岩溶勘察为实例,对原始资料进行了精细分析、整理和反演解释,结合实测地质剖面,得到了一些有意义的成果：圈定了场地内的不良地质现象;且场地岩溶较发育,其发育深度一般在10~30m之间,主要为充填溶蚀裂隙,局部存在溶洞,为新厂区的勘察、设计和施工提供了科学的基础地质资料。最后建议对场地的物探勘查进行钻孔加以验证,供后续施工参考。In order to verify the application effect of high density resistivity and seismic imaging method in karst exploration,this paper compares the application of the two methods to the karst exploration,and analyzes the characteristics of the karst apparent resistivity section and the image features of the ground seismic image.In this paper,taking the karst investigation of Guilin metallurgical plant as an example,the original data have been accurately analyzed,sorted,inverted and interpreted.Combining with the measured geological section,some meaningful results are obtained：the bad geological phenomenon in the field is delineated;and the site of the karst is developed with the development depth between 10 and 30 meters,which is mainly filling fissures and locally karst cave.This research can provide basic scientific geological data for the survey,design and construction of the new factory.Finally,it is suggested that the geophysical exploration of the site should be verified,and the reference for future construction is provided.
