- 本文根据有关文献[1] ,[2] 、[3] 、[4] 等,综述了由于基础环向不均匀沉陷而引起的浮顶罐上部成椭圆形的评价方法及其实验结果。本文给出了理论分析的数值计算机程序,计算结果与实测值有很好的吻合性。利用该程序可以根据实测的环向沉陷值确定罐基础的环向沉陷特性,以预计引起的椭圆度大小。对于此类沉陷的最大允许值也进行了讨论,以便统-要求,有利于设计和施工。
This paper recommends a method of assessing the effect of foun-dation settlement upon the ovality at the top of floating roof storage tanks. The author gives a calculating program which is used in pracice. The calculated results are identical with the ovality measurements in the test. The characteristic of circumferential settlement can be de-fined through the use of this program according to the measuring figues of settlements, and the ovality can be ealalculated in advance. The maximum permissible value on settlements is also discussed in order to reach a common understanding. It is advantageous to the design and construction of large tank.1988,1(1): 23-28 收稿日期：1987-7-10参考文献：
