  1. This paper introduces the development and present situation of vibration absorb technology in the world ; generally analysis the rubber - bearing ( rb ) and lrb " s operative mechanism, function and the calculation of parameter ; advance the concept of standardization to lrb ; on the basis of generally analyzing the connected factor such as the site category, the diameter of lead bar, the height of bearing, the designing carrying capacity, the span of bridge, the inherent period and the displacement of rb, determine the parameter, the absorbing vibration target, the method and the process of standardization to lrb ; then according to the two - step rule of resisting and defending earthquake, and combining with the response spectrum theory in the seismic vibration of bridge, make a lot of calculation and analysis of vibration absorb design to the real bridge collected and combined by finite element program ; at last, gives the result of standardization through diagram and explains to its usage

    本論文介紹了國內外減震技術的發展和現狀;綜合分析了普通板橡膠和鉛銷橡膠的工作機理、性能及參數的計算;提出了鉛銷橡膠標準化的概念;在綜合分析場地土、鉛銷徑、高度、設計載力、橋梁跨徑、固有周期以及變位等影響因素的基礎上,確定了鉛銷橡膠標準化的參數、減震目標、方法和過程;並根據抗震設防兩階段原則,結合橋梁地震振動理論的反應譜法,運用有限元程序對收集和組合的實橋進行了大量減震設計的計算和分析;最後以圖表的形給出了鉛銷橡膠標準化的結果,並說明了其使用方法。
