Based on the successful examples of sealing water gushing of dissolved cave located in a limestone area,the reasons of gushing,the confirm of cave¢s position,cave design scheme and implement,examining effects and the summarized experiences are presented. The practical examples of grouting technique for treating gushing dissolved cave in limestone area are introduced by analyzing of the formation mechanism of the cave,theoretical analysis,construction technique scheme,and construction management planning used in the course of sealing the cave. The achieved results can provide references to other similar types of anti-leaping and basement reinforcement.
