圓形板式中陽橡膠支座是樹立在橋梁的上部結構與墩臺之間，是橋跨的支承部分，其功率是把上部結構的各樣載荷傳播到墩臺上，并無妨契合活載、混凝土中斷與徐變等要素發生的變位（位移和轉角），使上、下部結構的本質受力情形符合組織的結構估計圖式。橋梁支座最早必需有腳夠的裝載身手，以維護平安穩當地傳播支座反力。其次圓形中陽橡膠支座關于梁體變形(xing)（位(wei)移(yi)和(he)轉角(jiao)）的(de)(de)拘謹應(ying)盡(jin)大(da)概地(di)小，以契(qi)合梁體自(zi)在彈(dan)性及轉化的(de)(de)須要。末尾支座(zuo)應(ying)具(ju)有便于安頓(dun)、維護、維建和(he)互換的(de)(de)特(te)性。
