摘要
采用悬臂浇筑法施工的预应力混凝土连续梁桥在施工过程中的内力和位移变化较为复杂,为了确保桥梁施工质量和施工安全,必须进行桥梁施工监控,实现成桥后结构的内力和桥梁线形满足要求。以官渡河特大桥主桥为工程背景,实施了官渡河特大桥主桥的施工监控,保证了官渡河特大桥主桥成桥后的结构内力和桥梁线形满足要求。
The change of internal force and displacement of pre-stressed concrete continuous girder bridge by the cantilever casting method in the construction process are complicated.In order to ensure the construction quality anal safety of bridge,the construction monitor of bridge must be proceeded to realize the internal force of structure and the alignment of the bridge able to meet the requirements after the bridge is finished.Taking the main bridge of Guandu River Bridge as the engineering background,its main bridge is implemented of construction monitor and to guarantee the internal force of structure and the alignment of the main bridge able to meet the requirements after the bridge is finished.
