文克尔地基梁法是计算桩在惯性荷载和运动荷载共同作用下的横向响应的一种常用分析方法。然而，关于如何正确地表示负载电阻（即，p-y）特性。这种混乱源于观察到的现象和大量的液化土壤的p-y弹簧模型，试图解释这种变化的显着变化。为了开发一种实用而又广泛适用的方法，提出了一种简化的混合p-y弹簧模型。该混合模型结合了液化土壤的现有p-y弹簧模型的各个方面，适用于各种土壤类型、相对密度、桩/轴直径和载荷条件。与各种已发表的情况下，涉及单桩的历史比较表明，混合p-y弹簧模型提供了合理的估计响应的运动学和…
AbstractThe beam-on-Winkler foundation (BWF) method is a popular analysis approach for computing the lateral pile response resulting from both inertial and kinematic loading. However, there is significant uncertainty regarding how to properly represent the load-resistance (i.e., p-y) behavior of liquefied soils. This confusion stems from the significant variability observed with the phenomenon and the large number of p-y spring models for liquefied soils that have attempted to account for that variability. In an attempt to develop a practical but broadly applicable approach, a simplified hybrid p-y spring model is presented. This hybrid model incorporates aspects of existing p-y spring models for liquefied soil and is applicable to a wide range of soil types, relative densities, pile/shaft diameters, and loading conditions. Comparisons with a variety of published case histories involving single piles indicate that the hybrid p-y spring model provides reasonable estimates of response for both kinematic and...
