针对钢制焊接储罐设计人员如何选取设计规范进行不同条件下的储液晃动波高计算的问题,介绍了GB 50341-2003、GB 50761-2012与API 650-2013中关于储罐晃动波高的计算公式及其影响因素,主要分析了GB 50341-2003与GB 50761-2012中储液晃动基本周期对地震影响系数取值的影响及其差异,对10×104 m3、1×104 m3及200 m3储罐进行了储液晃动基本周期、地震影响系数和储液晃动波高的计算,计算结果表明:相同容积与径高比的储罐晃动基本周期相同;储罐径高比越大,GB 50761-2012、API 650-2013与GB 50341-2003计算所得的晃动波高相差越大;当径高比趋于1时,GB 50761-2012、API 650-2013与GB 50341–2003计算所得的晃动波高相差较小。根据计算结果,给出了各个储罐设计规范中晃动波高计算公式的适用范围。 Aiming at the problem of how to choose the design criterion for the steel welded storage tank designer to calculate the wave height of the liquid storage under different conditions, the calculation formulas for the wave height of the tank shaking are introduced in GB 50341-2003, GB 50761-2012 and API 650-2013 And its influencing factors, mainly analyzes the influence of the basic period of liquid sloshing in GB 50341-2003 and GB 50761-2012 on the influence of seismic influence coefficient and the difference between them. For 10 × 104 m3, 1 × 104 m3 and 200 m3 tanks The basic cycle of reservoir shaking, the influence coefficient of earthquake and the wave height of reservoir shaking were calculated. The calculation results show that the same basic period of tank shaking of the same volume and diameter to height ratio is the same; API 650-2013 and GB 50341-2003 calculated the greater the difference between the sway wave height; when the diameter to height ratio tends to 1, GB 50761-2012, API 650-2013 and GB 50341-2003 calculated sway wave height difference is small. According to the calculation results, the applicable range of the wave height calculation formula for each tank design is given.
