摘要

深入分析了逆做法施工刚性桩复合地基在封桩前后的承载特性，推导出桩土应力比和桩身中性点深度计算公式。分析表明，对于逆做法刚性桩复合地基，调节桩土应力比（或桩土荷载分担比）可通过控制桩土间的沉降差（即封桩时间）、置换率及桩长来实现。进行复合地基设计时应由变形控制。由一工程实例的实测结果验证，计算值与实测值吻合程度很高。

Abstract

The loading behaviors of the rigid piles-composite foundation by reverse construction process before and after sealing piles are analyzed respectively; and equations to calculate the stress ratio and the depth of the neutrality point are deduced. Based on the analysis results

the stress ratio (or load sharing ratio) can be adjusted by controlling the settlement difference between piles and soils

the replacement ratio and length of piles. Deformation is the main factor in design of rigid piles-composite foundation. A practical example shows that the calculation results are satisfied compared with the testing results.
