感谢谢新宇先生对拙作的讨论 ,现答复如下。(1)如原文所述 ,轴、横向荷载同时作用下 ,桥梁基桩桩身挠曲变形比单一荷载作用下更大 ,桩 -土受力特性亦发生变化 ,按常用的线弹性地基反力法无法反映桩侧土体的非线性特性 ,因此原文引入有限元 -有限层理论进行分析 ,以克服文克尔地
Thank you, Mr. Xie Xinyu for his discussion on my book. My reply is as follows. (1) As mentioned in the original text, under the simultaneous action of shaft and transverse load, the deflection of pile foundation of bridge foundation is greater than that under single load, and the stress characteristics of pile-soil also change. According to the commonly used linear elastic foundation reaction force Method can not reflect the nonlinear characteristics of the pile side soil, so the original introduction of finite element - finite layer theory for analysis to overcome the Wenker
