引言

頂推施工方法在國內橋梁建設工程中已發展成熟，主要應用于橋梁上部結構跨越各種障礙物的施

工，分為拖拉式、推移式、步履式等多種頂推形式。頂推施工方法具有不中斷橋下交通、材料設備可重

復利用、施工效率高、便于空中姿態風險監控等優點，在跨越河道、山谷、既有線以及橋區場地環境受限

的橋梁建設中具有明顯的優勢，近些年來得到了很好地應用。但隨著橋梁跨度不斷增大、橋型結構愈

發復雜、頂推梁體更重、安裝精度越來越高等特點，且步履式頂推施工目前還沒有專門的規程或指南可

以參照。因此，結合建設行業采用步履式頂推施工方法進行橋梁安裝的實際需求，制定本文件。

本文件系為指導步履式頂推施工方法，統一安全、質量及技術標準要求，規范現場施工作業行為，

在總結該類橋梁建設經驗基礎上編制而成的，同時結合已有的工程實踐經驗，對步履式頂推施工的關

鍵環節和具體控制指標進行了規定。本文件僅限定了步履式頂推施工，不涉及主梁和梁體本身的附屬

結構工程施工。除能滿足步履式頂推施工的工程外，其他需采用步履式頂推裝置進行安裝的類似大型

構件亦可參考本文件相關內容。
