列车振动荷载作用下高速铁路近距地铁平行隧道的动力响应特性分析
Research on Dynamic Response of High-speed Train Vibration in Parallel Tunnel close to Metro
摘要
Abstract
In order to study the influences of the vibration generated by trains running on high-speed railway line and metro line at different speed on the lining structure of high speed railway tunnel, simulated vibration of the trains is employed to study the dynamic response characteristics of the high speed railway tunnel lining with simulated vibration load of trains imposed on the wheel axle via the rail in the same direction and at different train speed. The results show that under train vibration load, for a specific monitoring point of the tunnel, there is an influencing zone of train running vibration response, and the vibration response is the highest when a train reaches the monitoring point. The vibration response at the middle cross section of the high-speed rail tunnel increases gradually from up to down and the maximum vertical stress amplitudes of arch footing and invert are 1. 63 and 2. 26 times that of the haunch respectively, and maximum accelerations are 1. 21, 1. 29 times that of the haunch respectively.关键词
