| 摘 要： | 本文提出了实散组合桩概念，即一根桩由上下两段组成，上段是实体桩，下段是散体桩。这样就克服了散体桩通常桩头承载能力低的缺陷。本文对实散组合桩的受力概念进行了分析研究，给出了其承载力、沉降、临界桩长等计算方法和公式。最后介绍了首次工程实例。

| Abstract: | A concept of cement loose composite pile is proposed in this paper, that is a pile consists of two parts, the upper is a cement pile and the lower is loose material pile, so that the defect caused by low bearing capacify of loose material pile can be removed by this method. The concept of bearing of cement loose composite pile is studied and a calculation method and a formula of the bearing capacity, settlement, and critical lengh of the pile are suggested. At last, the first engineering case is introduced. |
