摘　　要：阐述3种验收标准提到的甲板横梁开孔的要求,不同标准对开孔位置远离面板距离各有不同,开孔的大小要求也有所区别,补强方式设计更灵活。结合现场的开孔设计及补强方法,采用力学计算模型及规范计算模型,编写电子表格进行计算,对比分析计算各种模型的剖面模数和惯性矩,在设计及施工中衡量哪种强度系数更高,确定合适有效的补强方式。The requirements of the three acceptance criteria for the hole in web beams were expounded,which is different the panel distance to the opening position,different from the size of opening;and the design of reinforcing way is more flexible.Combined with the field opening design and reinforcement method,the theoretical and standard calculation models were established.The Excel program was compiled to calculate and analyze comparatively the sectional modulus and moment of inertia from both models.According to the strength coefficient,the rational way of reinforcement can be determined.
