平板式桥梁橡胶支座自1965年起先后在上海、广东、山东、广西、福建、江苏、浙江等省市的部分公路与城市桥梁上试用以来,目前已成为国内中小跨径公路与城市桥梁上广泛采用的一种支座型式。近二十年的实地使用经验表明:平板式桥梁橡胶支座不仅工作性能可靠,而且与其他刚性支座相比,还具有构造简单、材料来源充足、加工制造容易、造价低、用钢量少、建筑高度小、安装使用方便、适用范围广、能吸收部分振动减少活载对桥跨结构及墩台冲击作用等许多显著的优点。有关设计计算数据已列入交通
Since 1965, the flat bridge rubber bearing has been used on the bridges of some highways and cities in Shanghai, Guangdong, Shandong, Guangxi, Fujian, Jiangsu and Zhejiang provinces and cities, and has now become the bridge of medium-sized and small-scale domestic roads and cities Widely used as a bearing type. Nearly two decades of field experience shows that the flat bridge rubber bearing is not only reliable in working performance but also has the advantages of simple structure, abundant material sources, easy manufacturing, low cost and small amount of steel compared with other rigid bearings , Small building height, convenient installation and use, wide application, and can absorb some vibrations to reduce the obvious advantages of live load on the bridge structure and pier impact. The design calculations have been included in the traffic
