摘要
对南京地铁南京站站的开挖施工引起的铁路轨道变形 ,采用车辆 -轮轨系统耦合动力学非确定性激扰模型 ,就南京地铁车站的开挖施工期间沪宁铁路客、货列车的限速和施工期允许的轨道最大变形量进行计算分析 。
In allusion to the problem of track distortion caused by under construction of Nanjing metro station,a model of vehicle/track undefined excitation was created based on vehicle/track coupling dynamics.The restricted speeds of passenger and goods trains of the Hu-Ning railway and critical value of track distortion during the construction of Nanjing metro station were calculated and analyzed.The reasonable restricted speeds of the trains were presented.
