修建(jian)彈(dan)(dan)性(xing)縫(feng)即彈(dan)(dan)性(xing)縫(feng)，是(shi)指為(wei)防止修建(jian)物(wu)(wu)構(gou)(gou)件(jian)因為(wei)氣候溫度(du)改變（熱脹、冷(leng)縮），使結(jie)構(gou)(gou)產生裂痕或毀壞(huai)而沿(yan)修建(jian)物(wu)(wu)或許(xu)構(gou)(gou)筑(zhu)物(wu)(wu)施工縫(feng)方向(xiang)的(de)(de)恰當部位設(she)置的(de)(de)一條結(jie)構(gou)(gou)縫(feng)。彈(dan)(dan)性(xing)縫(feng)是(shi)將基礎以上的(de)(de)修建(jian)構(gou)(gou)件(jian)如墻(qiang)體(ti)、樓板、房頂（木房頂除外(wai)）等分紅兩個(ge)獨(du)立部分，使修建(jian)物(wu)(wu)或構(gou)(gou)筑(zhu)物(wu)(wu)沿(yan)長方向(xiang)可做程度(du)彈(dan)(dan)性(xing)。那么彈(dan)(dan)性(xing)縫(feng)要(yao)怎么運用呢？

    彈(dan)性(xing)(xing)縫(feng)(feng)(feng)運用方法：因為施(shi)工(gong)(gong)(gong)(gong)人員(yuan)對(dui)彈(dan)性(xing)(xing)縫(feng)(feng)(feng)設(she)(she)備(bei)(bei)的施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)沒有足夠重視，未能(neng)嚴峻(jun)操控施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)和(he)標(biao)準，并按(an)設(she)(she)備(bei)(bei)程(cheng)序(xu)及有關(guan)操作(zuo)懇求施(shi)工(gong)(gong)(gong)(gong)，致使彈(dan)性(xing)(xing)設(she)(she)備(bei)(bei)不能(neng)正(zheng)(zheng)常作(zuo)業；（2）彈(dan)性(xing)(xing)縫(feng)(feng)(feng)設(she)(she)備(bei)(bei)設(she)(she)備(bei)(bei)是(shi)修建施(shi)工(gong)(gong)(gong)(gong)最后幾(ji)道(dao)工(gong)(gong)(gong)(gong)序(xu)之一，為了趕(gan)完工(gong)(gong)(gong)(gong)通車，無視內部(bu)質(zhi)量(liang)管理，施(shi)工(gong)(gong)(gong)(gong)人員(yuan)疏(shu)忽大意，彈(dan)性(xing)(xing)設(she)(she)備(bei)(bei)錨(mao)固(gu)鋼(gang)筋(jin)焊接(jie)不行健壯或產生遺漏(lou)預埋鋼(gang)筋(jin)現象，梁端彈(dan)性(xing)(xing)縫(feng)(feng)(feng)間距人為地放大和(he)削減，定(ding)位(wei)角鋼(gang)位(wei)置不正(zheng)(zheng)確(que)，給彈(dan)性(xing)(xing)縫(feng)(feng)(feng)木(mu)身(shen)構成危險，質(zhi)量(liang)不能(neng)確(que)保。

    彈(dan)性(xing)縫(feng)(feng)設備兩邊混凝(ning)(ning)土(tu)太薄，體積小，加(jia)上預埋(mai)件(jian)(jian)攪擾，施(shi)(shi)工難度(du)大，澆筑不(bu)密實，混凝(ning)(ning)土(tu)內(nei)部存在(zai)空泛(fan)、蜂窩，達不(bu)到(dao)設計所懇求(qiu)強度(du)，運用過程中，受車輛(liang)荷載的激(ji)烈(lie)沖(chong)擊(ji)，出現(xian)(xian)裂紋、開裂，逐步(bu)出現(xian)(xian)坑槽，如不(bu)及時(shi)(shi)處置，將(jiang)會引起錨固件(jian)(jian)的損壞。彈(dan)性(xing)縫(feng)(feng)設備兩邊混凝(ning)(ning)土(tu)與(yu)瀝青混凝(ning)(ning)土(tu)橋而鋪裝層別離(li)欠好，碾壓不(bu)密實，構成兩張皮(pi)，在(zai)車輛(liang)荷載重復沖(chong)擊(ji)效果(guo)下，簡單產生(sheng)開裂、零落，終究惹起彈(dan)性(xing)設備損壞。在(zai)焊接(jie)錨固件(jian)(jian)時(shi)(shi)，施(shi)(shi)工人員只重視外表(biao)，無(wu)視內(nei)部質量懇求(qiu)，槽口不(bu)ffi,沖(chong)洗不(bu)潔(jie)凈，焊接(jie)長度(du)不(bu)行，構成彈(dan)性(xing)縫(feng)(feng)設備錨固不(bu)健壯，經不(bu)住高速(su)重載車輛(liang)的沖(chong)擊(ji)、轟動。
