摘要

考虑到土壤的弹塑性行为，提出了一种用于单孔桩沉降预测的工程方法。该方法基于 Botkin-Kondner 双曲线模型。该工程方法与超固结土中钻孔长桩荷载试验结果进行了比较。考虑到土壤非线性行为的单桩沉降预测更为精确。完善了过固结土中桩轴阻力的减摩系数。

Single Bored Pile Settlement Prediction Taking into Account the Elastic-Plastic Behavior of the Soil

An engineering method for single-bored pile settlement prediction considering the elastic–plastic behavior of soils is proposed. The method is based on the Botkin–Kondner hyperbolic model. The comparison of the engineering method and bored long pile load test results in overconsolidated soil is presented. The single-pile settlement prediction taking into account the nonlinear behavior of soils is more accurate. The friction reduction coefficient of the pile shaft resistance in overconsolidated soil has been refined.
