摘要在paksey大橋的施工過程中，對節段梁的預制、節段梁的懸臂拼裝以及橋面體系的施工進行了精密的測量控制，從而使橋面線形與設計線形的誤差最小。 -
With reference to the cantilever erection of the continuous steel box girder of zhuanxing road overhead bridge crossing shenfengjin expressway in shanghai, this paper mainly describes the application of plc - controlled hydraulic sync jack - up system to the balanced cantilever erection of the box girder, closure construction of the girder at midspan, and the operation, control key points and corresponding technical requirements for application of the system
摘要結合上海莘奉金高速公路顓興路跨線連續鋼箱梁懸臂架設施工，重點闡述了plc控制液壓同步頂升系統在鋼箱梁「對稱懸拼，跨中合龍」中的應用及操作控制要點、技術要求。 -
This paper emphasizes on the construction control of concrete arch bridge, which is constructed by the precast segmental cantilever method. through analyzing this new erection method, it is considered that the cable forces directly influence the stresses of arch rib sections and the deflections of the arch axis, in addition, the stress of the arch rib section is the key factor in construction control
本文以懸臂拼裝鋼筋混凝土拱橋的施工控制為研究對象，結合工程實例，分析了大跨徑鋼筋混凝土拱橋的懸臂拼裝施工方法，認為施工過程中拉索的索力直接影響拱肋截面的應力和拱肋軸線的標高，拱肋截面的應力是懸臂拼裝拱橋施工控制的關鍵因素。 -
This paper presents the design method for a long span concrete continuous girder bridge with precast segments, mixed arrangement of internal and external tendons, and to be constructed with cantilever erection by overhead launching gantry, and also discusses several issues of the type of the bridge in need of special considerations in aspect of design calculations and constructional design
摘要介紹採用節段預制架橋機懸拼施工，採用體內、體外混合配束的大跨度混凝土連續梁僑的設計方法，對設計計算及在構造設計上需要特殊考慮的一些問題進行了探討。 -
Self - erection system is applied to construction of most of modern large span concrete bridges. in the process of construction, cantilever beam is changing continuously because of the gravity of concrete, the stretching force, the load and temperature variation etc. in order to ensure that two cantilevers constructing opposite can normally close up and that the bridge linearity can accord with design, flexibility deformation has to be monitored
現代大跨度混凝土橋梁多採用自架設體系施工，在混凝土自重、張拉力、橋面荷載、溫度變化等的作用下，懸臂梁體處于不斷的變化之中，為保證對向施工的兩端懸臂能正常合攏和控製成橋線形符合設計要求，需要對施工過程中的撓度變形進行監測。
