摘要

第二次世界大战末期朝鲜半岛的双对角桁架桥，是日本选府铁路局新开发的抗空袭(轰炸)结构类型。根据铁路局工程师的回忆录和1940年前的技术杂志，包括新发现的原始图纸，对发展和建设进行了总结。为了提高抗空袭性能，强烈建议采用内外静不定式、悬架结构等不同技术的多样性(组合)。最后介绍了中朝鸭绿江大桥的设计、施工过程及其抗空袭性能。

DEVELOPMENT OF DOUBLE DIAGONAL TRUSS BRIDGES BY RAILWAY BUREAU OF THE GOVERNMENT-GENERAL OF CHOSEN AND THEIR AIR RAID RESISTANT PERFORMANCE

Double diagonal truss bridges in the Korean Peninsula during the end of World War II were newly developed as an air raid (bombing) resistant structural type by Railway Bureau of the Government-General of Chosen, Japan. The development and the construction were summarized based on memoirs by engineers of Railway Bureau and technical magazines before 1940, including the newly discovered original drawings. To improve the air raid resistant performance, diversity (combination) of di ﬀ erent technologies such as internal and external statically-indeterminant, suspension structure and etc. was strongly recommended. Finally the process of design and construction of Yalu river bridge between China and North Korea and its air raid resistant performance were described.
