| 摘 要： | 速度锁定支座是一种把速度锁定器安装在支座上的抗震保护装置,该装置在正常工况下为桥梁提供承载、位移、转角等功能;地震时起到分担地震水平力、保护桥墩的作用。5.12汶川特大地震以后,为加快灾后重建,促进灾区经济社会发展,铁道部与成都市人民政府共同建设了成都至都江堰轻轨(以下简称成灌线)。本文通过速度锁定器支座在成灌线的应用,对该产品的结构、抗震性能进行阐述。

| Abstract: | Lock-up bracket is a seismic protection device with the lock-up device installed on bracket.Under normal conditions,the device provides load,displacement,and turning.When earthquake occurs,it can share the earthquake horizontal force and protect bridge piers.After 5.12 Wenchuan earthquake,in order to speed up the post-disaster reconstruction,and promote economic and social development in the disaster area,the ministry of railways and Chengdu authority jointly build the Chengdu—Dujiangyan light rail(hereinafter referred to as the Chengdu—Guanjiang line).This paper describes the application of lock-up bracket,and its structure and seismic performance. |
