非线性土体桩土相互作用对高桩码头抗震设计影响的分析

A Study on Effects of Nonlinear Soil-Pile Interaction Upon Aseismic Design of Piled Wharf Pier

针对目前高桩码头抗震设计中所存在的桩土相互作用对桩受力问题进行了分析,采用了非线性土p-y曲线桩土相互作用模式,编制了计算程序。通过实例分析表明对中强地震区,中软岸坡情况,桩土相互作用对桩受力的影响是显著的。

The effects of nonlinear soil-pile interaction on the aseismic design of piled wharf pier is studied. Nonlinear p -y curve is adopted in the modelling of the soil - pile interaction and a computing program is complied. From the results of analysis of an example.it is shown that the effect of soil -pile interaction on the pile internal force in medium to strong earthquake zones for piers on medium soft slope soil is quite significant
