貝雷橋工(gong)程(cheng)作出(chu)(chu)了幾(ji)個施工(gong)當(dang)中(zhong)問題可能會(hui)(hui)產(chan)生(sheng)斷(duan)(duan)樁現(xian)(xian)象(xiang)：第(di)一點：灌(guan)注時間(jian)過(guo)(guo)長或(huo)者(zhe)(zhe)導(dao)(dao)(dao)管在(zai)混凝(ning)(ning)土中(zhong)埋入(ru)過(guo)(guo)深，都會(hui)(hui)導(dao)(dao)(dao)致混凝(ning)(ning)土在(zai)導(dao)(dao)(dao)管內外壁上初凝(ning)(ning)，造(zao)成(cheng)混凝(ning)(ning)土與導(dao)(dao)(dao)管間(jian)摩擦阻力過(guo)(guo)大，上拔導(dao)(dao)(dao)管后(hou)混凝(ning)(ning)土不能及時填(tian)充，從而填(tian)入(ru)泥漿產(chan)生(sheng)了斷(duan)(duan)樁。第(di)二(er)點：混凝(ning)(ning)土自身(shen)的原(yuan)因(yin)，由于混凝(ning)(ning)土在(zai)拌和(he)過(guo)(guo)程(cheng)中(zhong)不均勻或(huo)者(zhe)(zhe)在(zai)運輸過(guo)(guo)程(cheng)中(zhong)產(chan)生(sheng)離析現(xian)(xian)象(xiang)，都會(hui)(hui)導(dao)(dao)(dao)致在(zai)灌(guan)注過(guo)(guo)程(cheng)中(zhong)出(chu)(chu)現(xian)(xian)粗集(ji)料集(ji)中(zhong)的現(xian)(xian)象(xiang)，造(zao)成(cheng)導(dao)(dao)(dao)管堵(du)塞而出(chu)(chu)現(xian)(xian)斷(duan)(duan)樁。第(di)三點：如果在(zai)灌(guan)注過(guo)(guo)程(cheng)中(zhong)護筒底腳(jiao)周(zhou)圍出(chu)(chu)現(xian)(xian)漏水(shui)(shui)或(huo)者(zhe)(zhe)由于缺乏施工(gong)經驗(yan)，都有可能出(chu)(chu)現(xian)(xian)坍孔現(xian)(xian)象(xiang)也(ye)會(hui)(hui)引起斷(duan)(duan)樁。第(di)四點：在(zai)施工(gong)過(guo)(guo)程(cheng)中(zhong)，由于各(ge)種原(yuan)因(yin)無法保證施工(gong)連續進(jin)行，比如導(dao)(dao)(dao)管進(jin)水(shui)(shui)、機(ji)械故障、停電(dian)等也(ye)會(hui)(hui)導(dao)(dao)(dao)致斷(duan)(duan)樁的發生(sheng)。
