这项工作的主要目的是利用从三维参数研究中获得的经验来开发一个简化模型，该模型将再现单桩行为的主要非线性特征，以及双桩之间的相互作用。因此，在该参数研究结果的指导下，本文提出了一种由耦合、非弹性支撑的一维桩组成的简化模型。该模型考虑了桩土之间的滑移和分离，以及包括退化在内的土体整体非弹性性态。通过与更精确的三维研究的数值结果以及实验现场测试结果的广泛比较来评估所提出的模型的有效性。这些结果与简化模型的预测结果非常吻合。这代表着朝着简化但现实的方法迈出了重要的一步。
The main objective of this work is to use the experience gained from a three‐dimensional parametric study presented in a companion paper to develop a simplified model that will reproduce the main nonlinear features of the behavior of single piles, as well as the interaction between a pair of piles. Hence, guided by the results of that parametric study, a simplified model consisting of coupled, inelastically supported one‐dimensional piles is developed and presented herein. This model takes into consideration slippage and separation between the piles and the soil, as well as the overall inelastic soil behavior including degradation. The validity of the proposed model is assessed by an extensive comparison with numerical results from the more accurate three‐dimensional study, as well as with results from experimental field tests. Close agreement is observed between these results and the predictions from the simplified model. This represents an essential step towards a simplified, yet realistic, method of an...
