实践证明:橡胶支座具有制作简单、安装方便、性能良好等优点。目前,国内中小跨桥梁上已普遍采用板式橡胶支座(以下简称橡胶支座)。在多跨简支梁桥上使用橡胶支座后,为减少桥面接缝而将桥面分段连接,就成为一件简便易行的事,国内外桥梁工程中均已有所采用[1]。 Practice has proved that: rubber bearings with simple production, easy installation, good performance and so on. At present, plate rubber bearings (hereinafter referred to as rubber bearings) have been widely used on domestic small and medium span bridges. After the rubber supports are used on the multi-span simple-supported girder bridge, it is a simple and convenient task to connect the bridge deck sections in order to reduce the joint of the deck, and has been used in the bridge engineering at home and abroad [1 ].
