摘要
结合郑西客运专线新华山车站的桩板结构工点,利用SAP2000对桩板结构在恒载、列车荷载和温度荷载作用下的变形特性和内力分布规律进行系统分析,对具有不同设计参数的结构分别建立计算模型,通过计算分析各设计参数对结构的影响,从中得出荷载变形和内力分布的基本规律。埋入式连续桩板结构的最大荷载响应发生在结构端部;改变主要设计参数,既能改变荷载响应的数值大小,又可改变其分布规律。
Combined with pile-slab structural construction of Xinhuashan Station in Zhengzhou-Xi＇an PassengerDedicated Line,this paper carries out systematic analysis on deformation characteristics and internal force distribution rule of pile-slab structure under dead load,train load and temperature load with SAP2000.It separatelyestablishes calculation model for the structure with different design parameters and gets the basic rule of load deformation and internal force distribution through computational analysis of the influence on the structure from each design parameter.The maximum load response of embedded continuous pile-slab structure is found at the structure end.Changing the main design parameters can change both load response magnitude and its distribution rule.
