- 摘要:
- 本文根据20多年来浙江、上海、天津等沿海地区100余台大型油罐工程的现场实测资料分析和应用实践的研究，并参考各国文献、标准，提出油罐罐体变形的三种模式，分别给出建在软土地基上的浮顶罐、内浮顶罐和拱顶罐的罐基不均匀沉降允许值，探讨了我国现行地基规范尚无统一规定的储罐软土地基不均匀沉降控制标准。
Three kinds of models for deformation of oil tanks have been given in this paper based on the application experience and the field data of more than 100 large-size oil storage tanks in the coast areas: Zhejiang, Shanghai and Tianjin. Referring to the professional literature and specifications, the paper focuses on the maximum permit amounts of uneven settlement for floating roof tanks, internal floating roof tanks and 'arch-roof tanks on soft foundations. It discusses the standard for controlling the maxi-mum permit amounts of uneven settlement which makes up the current specification for storage tank foundations.1996 ,4(4): 17-21 收稿日期：1995-10-23分类号：TU433参考文献：
