运用梁轨相互作用基本原理,在考虑钢轨、桥梁和墩台相互作用的基础上,建立了桥上无缝线路的线桥墩空间一体化计算模型,用于对桥上无缝线路伸缩附加力、挠曲力、制动附加力、断轨力、梁轨相对位移及墩台纵向受力和变形的计算分析。为计算方便,以有限元软件ANSYS为计算平台,利用ANSYS参数化设计语言进行二次开发,编制了有砟轨道基础桥上无缝线路通用计算软件,可用于各种桥上无缝线路的设计计算。
Based on the basic principle of interaction between beams and rails, an integrated calculation model of bridge pier piers is established based on the interaction between rails, bridges and abutments. Force, flexural force, additional braking force, track-breaking force, relative displacement of beam-track and longitudinal force and deformation of abutment. For the convenience of calculation, the finite element software ANSYS is used as the calculation platform and the secondary development is carried out by using ANSYS parametric design language. The general calculation software of the seamless line on the ballastless track foundation bridge is prepared and can be used for various seamless bridges on the bridge Design Calculation.
