摘要

对铅芯橡胶双向隔震铁路桥梁在列车荷载作用下的力学性能进行了研究

针对双向隔震铁路桥梁中存在的问题

提出了设置限位器的解决方案

并对设置限位器的双向隔震铁路桥梁进行了车桥耦合动力响应分析。研究结果表明

采用常规隔震设计方法的铅芯橡胶支座在横桥向的初始刚度和屈服强度均不能满足规范要求

设置限位器后

双向隔震铁路桥梁的力学性能有了很大的改善

各项指标均满足列车运行安全性和平稳性要求。

Abstract

The mechanical properties of lead rubber bidirectional seismic isolated railway bridges under train loads were studied

and a real time modal synthesis method for researching the train-bridge coupling vibration responses of non-linear bridges was proposed.With respect to the problems in bidirectional seismic isolated railroad bridges

the solution by installing steel restrainers was presented

and then

the train-bridge coupling vibration dynamic response analysis of the bidirectional seismic isolated railway bridges with steel restrainers was carried out.The studies show that

when using the conventional isolation design approaches

the initial stiffness and yield strength of lead rubber bearing in the lateral direction cannot meet the requirements of the standard.However

after installing the steel displacement restrainer

the mechanical properties of bidirectional seismic isolated railroad bridges were improved greatly and each indicator can meet the demand of safety and stationarity for train operating.
