摘　　要：我国国家标准GB/T 151中的管板设计方法是国际上先进的计算方法,近40年的工程实践充分证明了其合理性和可靠性。文章回顾了如何推翻西德、前苏联方法,确立我国GB/T 151管板计算方法的过程,进而总结了如何以GB/T 151法为基础,经巧妙变通解决各种管板的计算难题的途径,同时指出了JB4732管板计算方法的一个欠缺,并展望了采用一次结构法对管板设计进行优化的良好前景。The design method of tubesheet in China national standard GB/T 151 is an advanced method in the world.The engineering practice in the past 40 years has proved the rationality and reliability of the method.This paper not only reviews the process of proving the errors in the tubesheet calculation method of the former West Germany,the Soviet Union so as to establish the correctness of the calculation method of tubesheet(GB/T 151),but also summarizes how to solve the calculation problem of the various special tubesheets based on the GB/T 151 tubesheet calculation method.Meanwhile,it points out a deficiency of JB 4732 calculation method.The apper also gives the readers a good prospect of using the primary structure method to optimize the tubesheet design.
