盆式橡胶支座是近年来发展起来的一种新型桥梁支座。国内去年初次在唐山新建滦河大桥上采用。这种支座具有良好的铰性、滑动性和较大的支承强度,与钢铰支座相比,具有钢材省、费用少等优点。据滦河大桥使用盆式橡胶支座与钢铰支座相比,用钢量相当于钢铰支座的六分之一,费用只相当于钢铰支座的三分之一,具有良好的技术经济指标。 Basin rubber bearings are a new type of bridge support developed in recent years. The first time in China last year was adopted on the newly built Luohe Bridge in Tangshan. This kind of bearing has good hingeability, sliding property and large bearing strength. Compared with the steel hinge bearing, it has the advantages of steel saving and less cost. According to Luhe Bridge, the use of potted rubber bearings is equivalent to one-sixth of the steel hinge bearings, and the cost is equivalent to only one-third of the steel hinge bearings. Technical and economic indicators.
