摘要： 建造在软土地基上的大型钢储罐易产生各种沉降变形,其中罐周不均匀沉降的影响最为不利.基于实测沉降数据考察变壁厚浮顶型钢储罐的稳定性.分别对整体不均匀沉降和局部不均匀沉降下的变壁厚浮顶罐进行几何非线性有限元分析,通过分析沉降-位移全过程响应,了解储罐在两类沉降下的失稳模态和失稳过程,并与相应的等壁厚储罐的分析结果进行比较,最后给出设计建议.

Abstract: Large steel storage tanks constructed in soft foundations are easy to generate various types of settlement deformation, among which the differential settlement beneath the tank wall is the most serious. This paper analyzes the stability behavior of large tapered floating-roof steel storage tanks according to measured settlements. Geometrically nonlinear finite element analysis is carried out on the tapered floating-roof tanks under the global differential settlement and local differential settlement. By analyzing the settlement-displacement response, it is found that the tank has different types of buckling mode and buckling procedure. Comparison between structural behaviors of tapered tanks and uniform tanks is also conducted. Finally, some suggestion on stability design of tapered tanks is given．
Key words: tapered steel storage tank    floating-roof tank    measured settlement    differential
