高钢栈桥设计与施工研究

摘要

In order to solve the problem ofthe influence of Tong-shun Riverflood seasonontheconstruc-tion of Tong-shun River Bridge,the idea of designing and construction of high steel trestleis put for-ward.Analysis onthe design idea,structure design,structurechecking,construction technology and construction points of the high steel trestle is performed,whichoffers reference for familiar proj ect.It not only has the advantage of convenientconstruction,but also meets the need of VI navigation.The feasibility and effectiveness of the design and construction method of high steel trestle bridge are proved.%针对通顺河大桥施工受通顺河汛期影响严重的难题，提出了高钢栈桥设计与施工的思想。通过对高钢栈桥设计思路、结构设计、结构验算、施工工艺及施工要点进行分析论证，结合通顺河大桥工程具体实例，不仅方便了施工，而且满足了通顺河 VI级通航的需要，证明了高钢栈桥设计与施工方法的可行性和有效性。
