摘　　要：某柳州污泥泵房地基溶洞数量多,溶洞顶板稳定性差,厚度大多小于3m,易使构筑物下沉、开裂,甚至坍塌,造成严重的后果。本文在对溶洞的特征进行详细分析的基础上,结合市政工程的特点,使用压力注浆法加固溶洞地基,取得了良好的处理效果,并积累了市政工程溶洞处理的成功经验。There are many caves in the foundation of a Liuzhou sludge pump house,the roof stability of the cave is poor,and the thickness is mostly less than 3m.If it is not treated,it will easily cause the structure to sink,crack,or even collapse,causing serious consequences.Based on the detailed analysis of the characteristics of karst caves and the characteristics of municipal engineering,this article discussed the method of pressure grouting to strengthen the foundation of karst caves;It applied in actual projects and achieved good treatment results,and accumulated municipal engineering successful experience of karst cave treatment.
