摘　　要：对某新建油库油罐底板边缘板翘边和大阴角卷材防水翘口处空鼓开裂产生的原因进行了分析:前者是由于基础不均匀沉降、局部沉陷以及油罐底板焊接工艺错误中的一项或多项共同作用;后者是由于选材较差或黏贴工艺不当。简述了油罐对基础的基本要求、油罐底板结构特征与结构要求,提出了采用顶升平差法修正油罐壁板周边基础不均匀沉降和采用弹性密封胶封堵补平翘边翘口的措施,取得较好效果。The causes of the edgewarping of the oil tank bottom plate and the hollowing cracking at the waterproof warping of the large internal corner coiled material in a new oil depot is analyzed.The former is due to one or more joint effects of uneven settlement of the foundation,local settlement and wrong welding process of the oil tank bottom plate.The latter is due to poor material selection or improper pasting technology.The basic requirements of the oil tank for the foundation,the structural characteristics and structural requirements of the oil tank bottom plate are briefly described,and the measures of using the top lifting adjustment method to correct the uneven settlement of the foundation around the oil tank wall plate and using elastic sealant to plug and fill the warped edge and mouth are put forward,which have achieved good results.
