摘　　要：对于圆形平盖上开孔,GB 150-1998和GB/T 150-2011针对不同的开孔情况分别进行了规定并给出了计算方法。本文通过几组工程案例的计算,对比并分析孔间距对平盖开孔补强的影响,并以三种压力工况为例,就两个标准中单个开孔和多个开孔(以两个为例)的使用范围进行比较及论述。同时,结合国外标准,讨论在实际工程设计中如何选用计算方法进行圆形平盖的开孔补强计算。For openings on circular flat covers,GB 150-1998 and GB/T 150-2011 respectively specify and provide calculation methods for different openings.Through the calculation of several groups of engineering cases,this paper compares and analyzes the influence of hole spacing on the reinforcement of flat cover openings,and takes three pressure conditions as an example to compare and discuss the application scope of single opening and multiple openings(taking two as examples)in the two standards.At the same time,combined with foreign standards,this paper discusses how to select the calculation method to calculate the opening reinforcement of circular flat cover in practical engineering design.
