摘　　要：为提高战时大跨度桥梁抢修抢建能力,阐述了现有应急抢修梁现状及存在的主要问题,并借鉴现代桥梁的各种结构技术,对可适用于大跨度应急抢修梁的结构进行对比分析,提出了大跨度应急抢修梁的新形式——拱式结构,并论证提出拱式结构抢修梁的战术技术指标和总体技术方案,并应用ANSYS软件对方案进行有限元分析。To improve rush - repair and construction capability of large - span bridges in the event of war, this paper pres- ents current situation and main issues of rush - repair beam, compares and analyzes several structures suitable for large - span, rush - repair beam based on structure techniques of modern bridges. It also puts forward a new form of large - span, rush - repair beam, namely arch structure, discusses technical index and initial technological scheme of repair beam within arch structure, and carries out finite element analysis of the scheme through ANSYS software.
