[提要]  對(duì)56m混凝土長(zhǎng)墻出現(xiàn)的貫穿性裂縫進(jìn)行了計(jì)算及成因分析。通過(guò)對(duì)2天拆模時(shí)的裂縫間距及寬度的計(jì)算，證明裂縫是由溫度驟降引起的，而拆模過(guò)早和水平澆筑距離過(guò)長(zhǎng)是事故的主要原因。為避免類(lèi)似的混凝土長(zhǎng)墻工程出現(xiàn)相似的情況，提出了施工措施建議。

The author analyzed the shrinkage cracks of the 56m long concrete wall. Through calculating the distance and the width of cracks after 2 days dismantling formwork, the result proves that the cracks are due to temperature-fall suddenly. The main reason is dismantling formwork too early and level pouring distance too long. It puts forward the guide suggestion for construction of similar concrete long wall.
