There are a few studies on welded wide plate test for railway steel bridges in the world so for. The authors design and test more than fifty welded wide plates made of usualbridge steel l6Mnq and l5MnVNq in China. Through testing and comparing with the characteristics of railway steel bridges,the Engineering GeneraI Yielding Criterion is developed.Based on the criterion for the two steels and their welded joints,the ranges of the criticallength of the penetrating cracks and surface defects are analyzed at various service-temperatures,The maximum permissible defect size 2am of the two weldments is calculated by COD design curve adapted to the railway steel bridges,and the defect evaluation program underfatigue load has been suggested.Taking a steel plate fracture by orthopaedics in a long spanrailway steel bridge for example,the paper points out that the excessive original defect size causes brittle unstable fracture.

国内外对桥梁钢结构开展的宽板试验研究尚不多见,本文用国内常用的桥梁钢16Mnq、15MnVNq设计试验了50多块宽板。通过试验比较桥梁钢结构的特点,提出了工程全面屈服准则。用这一准则分析了两种钢材及焊接接头在不同使用温度下的穿透裂纹、表面裂纹的临界长度范围。用适合于桥梁钢结构的CDD设计曲线分析计算了两种钢材焊缝的最大容许裂纹长度,并提出了受疲劳载荷作用下桥梁钢结构缺陷评定步骤。以某大跨度铁路桥梁钢板矫形断裂事故为例,分析指出产生脆性失稳断裂的力学原因是由于过大的初始裂纹长度所致

A suggestion about adding the checkout method of general stability of compression and flexion members in two directions is offered when the "Code for Design on Steel Structure of Railway Bridge and Culvert of China" is revised,on the basis of analyzing the foreign and domestic codes about the bridge steel structure design and considering scientific research design experiences and the actual situation of our country.The practical equation in this paper would link up smoothly with the equation in single direction of the old code.

在研究分析国内外有关桥梁钢结构现行设计规范的基础上,结合科研设计经验和我国铁路桥涵钢结构工程的实际情况,提出了应在修订我国《铁路桥涵钢结构设计规范》时增加双向受弯压挠构件总稳定性验算方法的建议。笔者所提出的实用公式能与原桥规单向受弯压挠构件稳定性验算公式圆顺地衔接起来。
