摘要：

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.
