板(ban)式橋(qiao)梁(liang)橡(xiang)膠支(zhi)座(zuo)(zuo)主要特點就(jiu)是可(ke)以很(hen)好(hao)的(de)(de)將(jiang)橋(qiao)梁(liang)上(shang)部(bu)(bu)結(jie)構反(fan)力可(ke)靠地傳遞給墩臺，還能適應(ying)(ying)梁(liang)端轉(zhuan)動(dong)及通(tong)過橡(xiang)膠支(zhi)座(zuo)(zuo)的(de)(de)剪切變(bian)(bian)形來適應(ying)(ying)大梁(liang)由溫差引起(qi)的(de)(de)伸縮變(bian)(bian)形。它與原用(yong)(yong)的(de)(de)鋼(gang)支(zhi)座(zuo)(zuo)相比有明顯的(de)(de)優點，主要表現在其結(jie)構簡單，用(yong)(yong)鋼(gang)量少，建筑高度低，安裝、更換方便，有較(jiao)長的(de)(de)使用(yong)(yong)期限；能適應(ying)(ying)寬橋(qiao)、曲線橋(qiao)、斜橋(qiao)等上(shang)部(bu)(bu)結(jie)構在各方面的(de)(de)變(bian)(bian)形。另(ling)外，當(dang)各種(zhong)車(che)輛(liang)通(tong)過橋(qiao)梁(liang)時(shi)，橡(xiang)膠支(zhi)座(zuo)(zuo)能均勻(yun)分(fen)布水平力，吸收部(bu)(bu)分(fen)振動(dong)，從(cong)而延(yan)長橋(qiao)梁(liang)壽命。

板式橡(xiang)膠支座的(de)分類(lei)與表示方法如下：
