摘要

钢悬臂桁架桥的拆除是一项复杂的工程，需要大量的工程来保证安全有效的拆除程序。这种序列通常包括各种临时工程，包括临时桁架构件，临时支撑塔，张力释放装置和重型部件的临时附件。本文以美国的三个例子为例，回顾了开发悬臂钢桁架桥梁拆除顺序和所需临时工程设计的设计和分析考虑因素。

Temporary works for dismantling steel cantilever truss bridges in the USA

Dismantling steel cantilever truss bridges is a complex operation that requires significant engineering to produce safe and effective dismantling sequences. Such sequences often include a variety of temporary works including temporary truss members, temporary support towers, tension-release devices and temporary attachments for heavy-lift components. This paper provides a review of the design and analysis considerations for developing a dismantling sequence for cantilever steel truss bridges and the design of required temporary works, with three examples from the USA.

期刊介绍： Civil Engineering, listed by the Web of Science, is the ICE''s flagship journal. Practical and diverse in its scope, it publishes overview papers for the non-specialist on any subject relevant to civil engineering today. Topics range from landmark projects to philosophical, ethical, environmental, management and safety issues. Peer review, copyediting, and colour publication by Civil Engineering are free. If accepted, published papers are easily found by Google search, as well as in specialist citation indexes. There is also the option of making your article open access, should you wish to. Published authors receive a free electronic copy of their article to share with their peers. Furthermore, as well exposure to ICE''s 91,000-strong membership, published papers are promoted via our social media channels, accessing the wider civil engineering community. It is free to submit a paper to this journal. Papers appear Ahead of Print (below) as soon as they are ready to be published. Ahead of print articles are fully citable. using the DOI system
