As a kind of poor geology,karst is harmful for road construction and often cause duration delaying and cost increasing.The scale,shape and the direction of karst can be determined by seismic CT,the seismic CT also has the advantages of fast,highe resolution ratio and emotional image,it,s used widely in karst exploration.In this paper,the application of seismic CT in solving road karst prospecting explained by engineering examples.
