摘要
结合芜湖长江大桥建造经验，讨论了韧强比对于防脆断设计的意义．指出，焊缝超强值限定，缺乏依据，可由韧强比控制焊缝强度上限。
The significance of the toughness/strength ratio for the design of anti-brittle failure is diseased on the basis of the constructive experience in the construction of Wuhu Yangtze River Bridge. It is pointed out that the limit of a super-strength value in a weld lacks .evidence, thus the upper limit of a weld strength may ie controlled by the toughness/strength ratio.
