| 摘 要： | 以湖北省某岩溶场地的高层建筑工程为例，对岩溶地区高层建筑桩基础的设计与施工进行了探讨，分析了复杂岩溶地区高层建筑桩基础的设计过程、溶洞的处理方法及桩基施工要点。 经过对比分析表明，冲孔灌注桩适应性强、承载力高，能钻穿溶洞达到稳定持力层，建议作为岩溶地区高层建筑的首选桩基础形式。

| Abstract: | With the high-rise building project of a karst site in Hubei Province as an example, the design and construction of pile foundations of high-rise buildings in karst areas were discussed. The design process of pile foundations for high-rise buildings in complex karst areas, the treatment method of karst caves, and the key points of pile foundation construction were analyzed. Comparative analysis shows that the bored pile has strong adaptability and high bearing capacity, and can drill through the karst cave to reach the stable bearing layer. Therefore, the bored pile is the preferred pile foundation form for high-rise buildings in karst areas. |
