摘要： 某高层建筑的地基持力层分布均匀且埋藏较浅、土层厚度较小，而持力层下部又有较好的土层，经方案比选，决定采用大直径扩底短桩，并通过静载荷试验进行了验证，验证结果表明，试验结果与计算值基本一致，设计是合理可行的。

Abstract: The large diameter short bored pile with expanded end has the cost advantage in site with a relatively thin compressible layer over the bearing soils. A case study is presented in this paper to demonstrate this application. The static load test indicates that the design is appropriate.
