在地震荷载作用下，为了研究桩身和自由场土体的响应情况，以及桩-土间间隙发展，借助OpenSees计算平台建立了桩-土间非线性和桩-土间固结两种模型。分别将加速度峰值为0.2g和0.4g的Elcentro和Kobe波输入两个模型中，结果表明：桩身的加速度峰值和自由场土体地表处的加速度峰值均是输入到模型中的加速度峰值的1.6倍以上，自由场土体对加速度有放大效应；桩-土固结模型中因土体塑性变形而产生的残余位移比桩-土非线性模型中的大，其模型中的桩-土间隙比非线性模型中的大。

Under seismic load,in order to study the response of pile body and free field soil,as well as the development of pile-soil gap,two models of pile-soil nonlinearity and pile-soil consolidation are established with the help of Open Sees calculation platform.Elcentro and K...MORE Under seismic load,in order to study the response of pile body and free field soil,as well as the development of pile-soil gap,two models of pile-soil nonlinearity and pile-soil consolidation are established with the help of Open Sees calculation platform.Elcentro and Kobe waves with peak acceleration of 0.2g and 0.4g ar...
