[摘要] 针对武汉康桥小区场区内复杂的地质条件，采取同一结构单元中端承桩和端承摩擦桩共同受力的桩基础方案。以正常使用荷载（即单桩承载力特征值）作用下桩基沉降变形相等为原则确定单桩承载力特征值并完成桩基础设计。连续的沉降观测结果表明，建筑物整体沉降均匀，符合国家规范要求。本工程的基础设计思路和方法可为同类复杂地质条件下的基础设计提供有益的参考。

Abstract: According to the complicated geological conditions in Kangqiao Courtyard in Wuhan, it introduces a formula of pile foundation by joint load carrying in both end bearing pile and end bearing friction pile in the same structural block. The principle to determine the eigenvalue of bearing capacity of single pile and accomplish the foundation design is that, the settlements in different pile foundation by the action of the regular service load (called eigenvalue of bearing capacity of single pile) are equal. The observation result of continuous settlement indicates that there is a uniform settlement across the whole construction, and it can meet the national code demand. The idea and method of the foundation design in this project are helpful to be referenced by similar foundation design in complicated geological conditions.
