圆形橡胶支座/矩形橡胶支座是桥梁上,下部结构的连接点,其作用是将上部结构的荷载顺适,安全地传递到桥墩台上去,同时保证上部结构在荷载,温度变化,凝土收缩等因素作用下的自由变形,以便使结构的实际受力情况符合计算图式,并保护梁端,墩台帽不受损伤.这就要求它具有足够的竖向刚度和弹性,能将桥梁上部结构的全部荷载可靠地传递到墩台上,并同时承受由荷载作用引起的桥跨结构端部的水平位移,转角和变形,减轻和缓解桥墩承受的震动,适应因温度,湿度变化引起的桥跨结构胀缩.
The circular rubber bearing / rectangular rubber bearing is on the bridge, the connection point of lower structure, its function is to load the adaptation of the upper structure, safe transfer to the pier table, while ensuring the temperature change of the upper structure under loads, deformation free, concrete shrinkage effect factors, so that the structure of the actual stress with the calculation of schema, and to protect the end of the beam, pier cap is not damaged. This requires that it has enough vertical stiffness and elasticity, can be the full load of bridge superstructure is reliably transmitted to the pier, and bear the load of horizontal displacement caused by the end of the bridge, and corner deformation, reduce and alleviate the pier bear vibration, due to temperature, humidity changes caused by bridge expansion and contraction.

就圆形橡胶支座/矩形橡胶支座的安装位置而言,虽然在使用中可以进行圆形橡胶支座/矩形橡胶支座更换,但更换的成本费用,技术性以及困难性均很大,桥梁中大部分圆形橡胶支座/矩形橡胶支座可谓是永久性的安装,圆形橡胶支座/矩形橡胶支座寿命应该与桥梁的寿命相吻合,否则会对桥梁的使用造成不良的后果,尽管在桥梁的成本造价中圆形橡胶支座/矩形橡胶支座成本仅占很小的比例,但作用远远超过其成本,为此,圆形橡胶支座/矩形橡胶支座就成为桥梁建设和使用的重要材料之一.
The installation position of the circular rubber bearing / rectangular rubber bearings, although can be used in a circular rubber bearing / rectangular rubber bearing replacement, but the replacement cost, and technical difficulty are great, most of the bridge circular rubber bearing / rectangular rubber support is a permanent installation of rubber bearings / round the life of rectangular rubber bearings and bridge life should be consistent, otherwise it will use to bridge the adverse consequences, in spite of the bridge cost in circular rubber bearing / rectangular rubber bearing costs accounted for only a small proportion, but the effect is far more than its cost, therefore, the circular rubber bearing / rectangular rubber bearing has become one of the an important material in bridge construction and use.
近年来在桥梁圆形橡胶支座/矩形橡胶支座使用过程中,圆形橡胶支座/矩形橡胶支座出现了各种各样的质量问题和质量隐患,究其原因可分为产品质量,施工质量和设计选型三方面.圆形橡胶支座/矩形橡胶支座支座的产品质量,施工质量和设计选型关系到圆形橡胶支座/矩形橡胶支座的使用寿命,需要生产方,施工方和设计方的紧密配合,任何一方出现问题都将严重影响圆形橡胶支座/矩形橡胶支座的使用寿命,
In recent years, the circular rubber bearing bridge / rectangular rubber bearings in the process of using circular rubber bearings / rectangular rubber bearings have quality problems and quality problems of all kinds, the reason can be divided into product quality, construction quality and design and selection of three aspects. The circular rubber bearing / rectangular rubber bearings bearing product quality, construction quality the design and selection of related to the service life of the circular rubber bearing / rectangular rubber bearings, need to work closely with the production side, the construction side and the design side, any problems will seriously affect the service life of the circular rubber bearing / rectangular rubber bearings,
