摘要
采用三维有限元数值模型对列车运行振动作用下某相邻水工建筑物的动力影响进行了分析,计算中根据列车实际运行规律,采用一种振幅逐渐增大的动力荷载函数,并提供了动力分析中地基反力系数和阻尼系数的计算方法,计算了在动力作用下列车振动对某相邻水工建筑物的影响,可对类似工程的分析提供参考.
The three-dimensional finite element numerical model of the train running under the effect of vibra- tion of a neighboring hydraulic engineering building power was analyzed. In the calculation, according to the law of train running, using a dynamic load function of growing amplitude, and put forward the dynamic analy- sis of the foundation of the force coefficient and damping coefficient calculation method, the calculation in the train vibration under dynamic action of a neighboring effects available to the analysis of the similar project to provide the reference.
