某特大桥跨越河谷，根据现场条件及施工要求，需在主墩之间架设跨度120m，高差及矢高均为12m的悬索便桥。为了保证结构安全，设计、造价合理，针对便桥，详细介绍了便桥的材料选用及整体布置，并对其进行了设计分析。结合分析结果并对施工方案进行优化，施工便桥成桥后，监测结果表明，内力和线形误差满足规范要求，施工便桥安全可靠。该项技术可为同类桥梁便桥设计、施工提供参考。
某特大橋跨越河穀，根據現場條件及施工要求，需在主墩之間架設跨度120m，高差及矢高均為12m的懸索便橋。為瞭保證結構安全，設計、造價閤理，針對便橋，詳細介紹瞭便橋的材料選用及整體佈置，併對其進行瞭設計分析。結閤分析結果併對施工方案進行優化，施工便橋成橋後，鑑測結果錶明，內力和線形誤差滿足規範要求，施工便橋安全可靠。該項技術可為同類橋樑便橋設計、施工提供參攷。

In accordance with field condition and requirements of construction, we need to erect a suspension auxil-iary bridge with a span of 120ms and a height difference of 12ms as well as a vector height of 12ms between the main piers of an extra-large cross-river bridge. To guarantee the structure safety, a reasonable design and cost, this paper dis-cusses the selection of the construction materials along with the overall plan of the auxiliary bridge and also analyzes the design of the bridge. Based on the results of the analyses, the construction plan is optimized. According to the surveil-lance result, the finished auxiliary bridge is safe and reliable with the errors of both the internal force and alignment meet the related standard requirements. Hence, these techniques can provide references to others on the design and construc-tion of bridges of the same kind.
