基于室内模型试验，对不同影响因素下岩溶区嵌岩桩的破坏模式进行研究，将其总结归纳为4类：冲切破坏、冒落区塌落破坏、扇形塑性区破坏和撕裂破坏，破坏模式主要与顶板厚度、溶洞赤道半径 b 以及 c/b 有关。通过对比各规范对岩溶区嵌岩桩设计的相关规定，结合模型试验结果，对溶洞顶板安全厚度的探讨进行延伸，并提出一系列安全可靠、便于岩溶区嵌岩桩设计的公式，并在工程实例中得到验证。

Based on indoor model tests,the failure mode of rock-socketed pile in karst area under different influencing factors is researched. The test indicate that there are four failure modes,which are punching failure mode,collapsed zone failure mode,sector plastic zone failure mode and tearing failure mode. Failure mode is mainly related with roof thickness,equatorial radius of karst cave,the ratio of polar radius to equatorial radius of karst cave. Compared with different specifications about the design of rock-socketed pile,investigate on cave safe roof thickness is extended;and a serious of credible computational formula are brought out,which are proved by engineering examples.
