摘    要:运用ABAQUS软件对京石客专声屏障桩基础在竖向荷载作用下的受力特性进行三维模拟,分析采用不同的桩长、桩径、桩身混凝土情况下,重点分析桩顶的位移和桩身内力的大小及分布规律。结果表明:本桩基础的竖向承载力很大,桩径的大小对桩的沉顶沉降影响比较大,桩长的大小对桩的沉降有一定的影响,桩身混凝土的强度对桩顶沉降影响较小。

关 键 词:声屏障  桩基础  数值分析  影响因素

Abstract:ABAQUS software was used for 3D simulation of bearing and deforming behavior of the sound barrier pile foundation under vertical load.The pile top displacement and the internal force were mainly analyzed,considering different values of the pile length,pile diameter and concrete type.The results show that the pile foundation has satisfying bearing capacity,the pile diameter has relatively important influence on the settlement of the pile,the pile length has some influence on pile's setting,and concrete intensity has little influence on the setting of pile top.
Keywords:sound barrier  pile foundation  numerieal simulation  influencing factors
