Abstract: This paper presents an anti wind design method and a formula with a verifying program based on the up dated theory of oil storage tank's anti seismic.Considering the specificity of the environment in beach strand oilfields,it is more reality to assume instantaneous wind speed of 3 seconds once in the span of 50 years as the calculation basis.Combining the computer aided design with the computer aided graphics,a CAD/CAG software package of oil storage tank are formed.This package can automatically retrieve data,quickly and precisely fulfil all the analysis and output the graphics without the troublesome data search for early days's manual calculation.The system is being put into practice.

Key words: oil storage tank soft, foundation, strength, design, computer graphics

摘要： 根据滩海油田地区环境条件的特殊性,认为取50年一遇的3秒钟瞬时风速作为计算依据更切合实际,给出了相应的抗风设计方法和设计公式,根据最新储油罐抗震理论编制了验算程序.将计算机辅助设计与辅助绘图集成一体,形成了一套完整的储油罐CAD/CAG系统.该系统省去了过去人工计算需要查取数据的麻烦,可以自动检索,并完成各项分析计算和全套施工图的绘制工作.速度快、准确性高,直接输出透明图,整洁规范.该系统正用于实际设计生产.
