橋梁彈性縫設備因為設置在梁端結構薄弱的部位，直接承受車輛荷載的重復效果，又多暴露于大天然中，受到各種天然要素的影響，因而，彈性設備是易損壞、難修補的部位。彈性設備發生破損的原因是多方面的，主要有：

    規(gui)劃(hua)不(bu)(bu)(bu)周規(gui)劃(hua)時(shi)梁端(duan)部未能慎重考(kao)慮，在重復荷載(zai)效果下(xia)(xia)，梁端(duan)破損引起彈(dan)(dan)性(xing)(xing)設(she)(she)備失靈(ling)。另外，有時(shi)變形量計算不(bu)(bu)(bu)恰(qia)當，選用了過大的(de)彈(dan)(dan)性(xing)(xing)間(jian)距(ju)，導(dao)致彈(dan)(dan)性(xing)(xing)設(she)(she)備破損。彈(dan)(dan)性(xing)(xing)縫設(she)(she)備自(zi)身(shen)問(wen)題(ti)彈(dan)(dan)性(xing)(xing)設(she)(she)備自(zi)身(shen)結構剛(gang)度(du)(du)(du)不(bu)(bu)(bu)足(zu)錨(mao)固的(de)構件強度(du)(du)(du)不(bu)(bu)(bu)足(zu)，在營運過程(cheng)(cheng)中(zhong)發生不(bu)(bu)(bu)同程(cheng)(cheng)度(du)(du)(du)的(de)破壞。對彈(dan)(dan)性(xing)(xing)設(she)(she)備的(de)后澆壓填材料沒有認(ren)真對待、精心挑選，致使彈(dan)(dan)性(xing)(xing)設(she)(she)備營運質量下(xia)(xia)降，發生不(bu)(bu)(bu)同程(cheng)(cheng)度(du)(du)(du)的(de)病害(hai)。

    彈(dan)性(xing)(xing)縫(feng)的(de)(de)施(shi)工(gong)與澆筑(zhu)施(shi)工(gong)過程(cheng)中(zhong)，梁(liang)端彈(dan)性(xing)(xing)縫(feng)間距(ju)(ju)沒有按規劃要(yao)求完結(jie)，人為地放大(da)和縮小，定位(wei)角(jiao)(jiao)鋼方位(wei)不(bu)正(zheng)(zheng)確，致使彈(dan)性(xing)(xing)設(she)備(bei)不(bu)能正(zheng)(zheng)常(chang)作(zuo)業。這樣會(hui)出現下(xia)列情況：因(yin)為縫(feng)距(ju)(ju)太小，橡膠彈(dan)性(xing)(xing)縫(feng)因(yin)超限揉捏凸起(qi)而發生(sheng)跳車(che)；因(yin)為縫(feng)距(ju)(ju)過大(da)，荷(he)(he)載(zai)效(xiao)果下(xia)的(de)(de)剪切力以及車(che)輛(liang)行進的(de)(de)慣性(xing)(xing)，會(hui)將松動的(de)(de)彈(dan)性(xing)(xing)縫(feng)橡膠帶出定位(wei)角(jiao)(jiao)鋼，發生(sheng)了(le)另一類型的(de)(de)跳車(che)。施(shi)工(gong)時(shi)彈(dan)性(xing)(xing)設(she)備(bei)的(de)(de)錨固(gu)鋼筋焊(han)接的(de)(de)不(bu)行牢(lao)固(gu)，或發生(sheng)遺漏預埋(mai)錨固(gu)鋼筋的(de)(de)現象，給彈(dan)性(xing)(xing)縫(feng)自身形成隱患；施(shi)工(gong)時(shi)彈(dan)性(xing)(xing)設(she)備(bei)裝置(zhi)的(de)(de)欠好，橋(qiao)面鋪(pu)裝后彈(dan)性(xing)(xing)縫(feng)澆筑(zhu)的(de)(de)欠好，使用過程(cheng)中(zhong)，在重(zhong)復荷(he)(he)載(zai)效(xiao)果下(xia)致使彈(dan)性(xing)(xing)縫(feng)損壞。

    接(jie)(jie)連(lian)(lian)(lian)(lian)縫(feng)(feng)設置(zhi)不(bu)(bu)(bu)行(xing)(xing)完(wan)善(shan)為(wei)了減少彈性縫(feng)(feng)，很多選用接(jie)(jie)連(lian)(lian)(lian)(lian)梁或接(jie)(jie)連(lian)(lian)(lian)(lian)橋面。橋面接(jie)(jie)連(lian)(lian)(lian)(lian)就需設置(zhi)接(jie)(jie)連(lian)(lian)(lian)(lian)縫(feng)(feng)，接(jie)(jie)連(lian)(lian)(lian)(lian)縫(feng)(feng)的設置(zhi)不(bu)(bu)(bu)行(xing)(xing)完(wan)善(shan)，致使接(jie)(jie)連(lian)(lian)(lian)(lian)縫(feng)(feng)破損(sun)，而(er)發(fa)生橋面跳車(che)。橋面接(jie)(jie)連(lian)(lian)(lian)(lian)縫(feng)(feng)處(chu)，變形假縫(feng)(feng)的寬(kuan)度(du)和(he)深度(du)設置(zhi)得不(bu)(bu)(bu)行(xing)(xing)規范，不(bu)(bu)(bu)行(xing)(xing)統一，這也不(bu)(bu)(bu)同程度(du)地影(ying)響著接(jie)(jie)連(lian)(lian)(lian)(lian)縫(feng)(feng)的正常作(zuo)業(ye)。
