连续梁桥现浇段施工技术分析

Analysis of Construction Technology for Cast-in-place Section of Continuous Beam Bridge

连续梁桥已广泛运用到公路工程及市政工程中。通常大家都比较重视连续梁的挂篮悬臂施工、0号块施工,而忽视了过渡墩现浇段的施工。现浇段施工质量高低是影响连续现浇梁施工质量的关键因素之一,对成桥后行车平顺度及桥梁耐久性影响至关重要。以某连续梁桥现浇段施工为例,对现浇段施工技术进行分析总结。

Continuous beam bridge has been widely used in highway engineering and municipal engineering.Usually,people pay more attention to the cantilever construction of continuous beams and the construction of No.0 blocks,while neglecting the construction of the cast-in-place section of transition piers.The quality of cast-in-place section construction is one of the key factors affecting the quality of continuous cast-in-place beam construction,which is crucial for the smoothness of driving and the durability of the bridge after completion.Taking the construction of a continuous beam bridge's cast-in-place section as an example,this paper analyzes and summarizes the construction technology of the cast-in-place section.
