摘要

新建线路下穿既有运营铁路的架空体系受运营列车动荷载的影响明显。为评价列车动荷载作用下既有运营铁路架空体系的安全性,依托经九路下穿陇海铁路立交工程,采用数值模拟和现场监测方法对既有运营铁路架空结构体系的动力响应进行研究。分别考虑了不同行车速度和不同轴重列车荷载的影响,从振动加速度、竖向位移和动应力三个方面分析了轨枕、横抬梁和架空桩的动力特性,并结合数值模拟和现场监测结果对既有线架空体系的稳定性进行了评价。结果表明,既有线架空体系对列车车速和列车轴重均有明显响应,架空体系对于列车速度变化的敏感性要比对列车荷载敏感性强;架空体系中的架空桩对列车速度和列车荷载变化的敏感性要比钢枕强;数值结果和监测数据均表明,架空体系的动力响应值均在允许范围之内。

Abstract

The overhead system of the new line under the existing operating railway is obviously affected by the dynamic load of the operating train. In order to evaluate the safety of the overhead structure system of the existing operating railway under the action of train dynamic load, relying on the overpass project of Jingjiu road under Longhai railway, the dynamic response of the overhead structure system of the existing operating railway is studied by using numerical simulation and on-site monitoring methods. Considering the influence of train load with different running speed and axle load, the dynamic characteristics of sleepers, cross lifting beams and overhead piles are analyzed from three aspects: vibration acceleration, vertical displacement and dynamic stress. The results show that the overhead system is more sensitive to the change of train speed than train load, and the overhead pile is more sensitive to the change of train speed and train load than steel sleeper. However, the numerical results and monitoring data show that the dynamic response values of the overhead system are within the allowable range, and the overhead construction is safe.
