- 某石化公司140万m3原油商业储备库项目14台10万m3浮顶罐全部采用倒装法进行罐壁在施工中因受到沙尘暴的影响，其中一台浮顶罐罐体严重移位，罐体西南侧约1/4离开基础脱离基础最远处为1.863 m，该罐直径为81 m,罐体移位时的高度为9.6 m，总质量370 t，文章以该储罐复位为例.介绍大型储罐采用多机抬吊法整体复位的施工工艺特点及施工过程中应注意的问题。
n a 140x104 m3 commercial crude oil depot project, the tank wall assembly construction of 14sets of 10x104m3 floating roof tanks applied entirely the inverted assembly method. Because the influence ofsand storm during the construction, severe displacement of a tank took place, that the southwest portion of thetank departed from its original foundation with the maximum displacement of 1.863 m. The tank diameter was81 m，its height was 9.6 m and its whole mass was 370t.The tank was positioned using the lifting methodwith multi cranes. The construction process features of the integral tank reposition by the method are describedin this paper, and the matters for attention in the construction are indicated as well.2009,5(5): 59-60,75 收稿日期：2008-11-24分类号：TE972作者简介：余雷(1980-)，男，河南南阳人，助理工程师，毕业于重庆石油高等专科学校内燃机专业.从事起重吊装工作。
