摩擦摆式隔震支座在我国已经逐渐推广应用,但对隔震支座用滑板在地震条件下的摩擦与磨耗性能缺少系统的试验研究,参照国外的试验方法对目前在公路桥梁支座中常用的聚四氟乙烯、改性聚四氟乙烯和改性超高分子量聚乙烯滑板,在模拟地震状态下摩擦性能进行试验研究。试验表明改性聚四氟乙烯是一种较适宜用于公路桥梁摩擦摆式隔震支座的滑板材料。 Friction type pedestal has been gradually popularized and applied in our country. However, there is no systematic research on the friction and wear performance of the pedestal with isolation bearing under earthquake conditions. With reference to the test methods abroad, Commonly used polytetrafluoroethylene, modified polytetrafluoroethylene and modified ultra-high molecular weight polyethylene skateboards, in the simulated earthquake state friction performance of experimental study. The experiment shows that the modified PTFE is a kind of skateboard material which is more suitable for the friction bridge bearing of highway bridge.
