摘　　要：对于复杂的地质条件,选择合理的基础形式至关重要。目前在岩溶地区,冲孔桩和嵌岩桩是最有效的钻进方法。通过工程案例,从顶板的稳定角度出发,对单一溶洞存在时桩基承载力的确定进行了分析,对冲孔灌注桩施工工艺进行了归纳总结。For the complicated geographical condition in karst areas, The form of the rational choice c,f foundation is very important. To the author＇ s knowledge, in karst area punching pile is the most effective method of drilling. Through the Pro- ject, from the roof of the stable point of view, On the single pile bearing capacity of karst cave was analyzed, and Construction Technology of hole- drilled bored Dries were summarized.
