摘　　要：针对大型无底座矩形容器整体吊装底板变形大的情况,采用临时拉筋连接底板与加强筋的方法增加无底座矩形容器的刚性,以控制整体吊装时的底板变形。利用大型有限元软件ANSYS对采用该法进行整体吊装的某实例工况进行分析计算,分析结果显示,采用临时拉筋利用罐体自身加强筋的刚性能有效控制无底座矩形容器吊装时的变形。In view of the situation of the large deformation for large non-base tank is not satisfied in the hoisting condition plate and the reinforcing tion of the bottom plate analyze and calculate the temporary pull bars by s for lifting , using the method rib to increase the r during the whole lif in elf of temporary igidity of th ting. The fi e reinforcement non-base tank connecting the b to control the def ottom orma nite element method ANSYS is used to tegral lifting condition of a certain example. The results show that the -stiffener rigid can effectively control the deformation of non-base tank
