带褥垫层减沉桩作用机理及现场实验研究

The Mechanism of Settlement Reducing Pile Foundation with Bedding Layers and in Site Experiments

本文对某采用带褥垫层的减沉桩基础工程进行了现场实测，通过桩反力和土反力的荷载传感器实测了桩、桩间土反力。整理并分析了实验数据，对桩土应力随荷载变化的过程、桩土共同作用机理及桩土荷载分担比的变化过程进行了全面的分析，并得出相关结论。

Experiments in the settlement reducing pile foundation with bedding layers were performed. Measurement of reactions of piles and nearby soils was conducted.The test data were sorted out and the stress development in the pile and nearby soils was analyzed.Meanwhile,the mechanism of pile-soil interaction and the bearing ratios in pile and nearby soils was analyzed in great details.Some interesting conclusions were drawn through the tset results.
