摘要
城市轨道建设的目的是改善一些大城市日常交通拥堵现象.近年来随着轨道交通的大力发展,越来越多的要求也在逐步提高,尤其是城市轨道交通大部分要穿过一些人口聚集区,比如机场、大型商场、医院、商务办公区等,这就对其运营产生的振动噪声提出更高要求,目前,我国针对不同地段减振方式各有不同,如一般减振、中等减振、高等减振、特殊减振方式.钢弹簧浮置板道床是利用内置式阻尼钢弹簧隔振器将道床顶升至一定高度来达到减振效果.
Abstract
The purpose of urban rail construction is to improve the daily traffic congestion in some large cities.In recent years,with the vigorous development of rail transit,more and more requirements have been gradually raised,especially for urban rail transit,which mostly passes through population gathering areas such as airports,large shopping malls,hospitals,business office areas,etc.This puts higher requirements on the vibration and noise generated by its operation.Currently,there are different vibration reduction methods for different sections in China,such as general vibration reduction,medium vibration reduction,and high vibration reduction,special vibration reduction method.The steel spring floating slab track bed uses a built-in damping steel spring isolator to raise the top of the track bed to a certain height to achieve vibration reduction effect.
