研究高速铁路双线简支梁桥的空间振动响应．建立了考虑双线简支梁在车辆蛇行和单线行车时的偏心荷载作用下车桥系统空间耦联作用的振动力学分析模型，以２０ｍ和４８ｍ简支梁桥为例，在计算机上模拟列车过桥的全过程，通过分析动力响应，得出了一些有工程意义的结论．
Study on Spatial Vibration Response of Double Track Simply Supported Beam Bridge on High Speed Railways. The vibration mechanical analysis model considering the coupling effect of the two-wire simply-supported beam under the eccentric load of the vehicle on the winding and the single-line vehicle was established. Taking 20m and 48m simply supported beam bridges as an example, The whole process of the bridge, through the analysis of dynamic response, draws some conclusions of engineering significance.
