摘要
中国在20世纪60年代开始栓焊钢桥的建设,但焊接钢桥的大发展却是在20世纪90年代以后。简要介绍了焊接钢桥在中国发展的几个阶段、发展水平以及若干技术进展,包括桥梁钢的开发及其焊接材料的优化、焊缝强韧性的控制标准问题。
The construction of bolted and welded steel bridges began in 1960s in China,but great development of welded steel bridges started after 1990s.This paper briefly introdces the several development stages,development level and some technical progress about the welded steel bridges in China,including the development of bridge steel ,optimization of welding material and the control standard problems of weld toughness-to-strength
