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。
Combining with the construction site of pile structure of Xinhua Mountain Station in Zhengxi Passenger Dedicated Line, the deformation characteristics and internal force distribution of pile structure under constant load, train load and temperature load are systematically analyzed by using SAP2000. The structure with different design parameters The calculation models are respectively established, and the influence of each design parameter on the structure is analyzed and calculated, and the basic laws of load deformation and internal force distribution are obtained. The maximum load response of buried continuous pile structure occurs at the end of the structure. Changing the main design parameters can not only change the value of load response but also change its distribution.
