摘　　要：新型铝合金桥梁建设在国内刚刚起步,面临一系列技术难题。为提高我国铝合金桥梁的设计和施工技术水平,该文针对我国已建的半开式铝合金桁架桥梁设计中的变形、应力、自振频率和屈曲特性进行了分析,比较了其不同于一般桥梁设计的特点。同时介绍铝合金桥梁施工的工艺要求和流程,对铝合金桥梁的设计和施工提出了合理建议。The construction of new aluminum alloy bridge is just started in China and faces a series of technical difficulties.In order to enhance the design and construction levels of the aluminum alloy bridge in China,the article analyzes the deformation,stress,self-vibrating frequency and flection characteristic in the design of the built semi-open aluminum alloy truss bridges in China,and compares the characteristics of the differences from the general bridges.At the same time,the article introduces the technological requirements and flows in the construction of aluminum alloy bridges,and puts forward the reasonable suggestions in the design and construction of aluminum alloy bridge.
