建筑物荷载对超长单桩基础影响的三维模拟分析

Analysis on Influence of Building Load on Ultralong Single Pile by 3D Simulation

以沿海地区甬台温复线ZK40段典型地层参数为依据,采用ABAQUS进行建模,模拟单桩基础在不同情况受建筑物荷载的作用。模拟结果显示,随着建筑物荷载的大小、距离、面积以及桩顶荷载的变化,桩基础的受力和位移也相应变化,验证了堆填土对桩基础的影响规律。

Based on the parameters of typical strata in the Section ZK40 of Yong-Tai-Wen Double Line in coastal areas,the model was established with ABAQUS to simulate the single pile under the action of building load in different cases.The result shows that,with the change of the magnitude,distance,area of building load and the load on the pile top,the force and displacement of the pile change accordingly,which validated the effect regularity of filling on the pile.
