摘要
采用挂篮悬臂浇筑施工的大跨径连续梁桥,合龙段是梁桥施工过程中最重要的关键环节,不同的合龙施工方案会给桥梁线形及主梁应力带来不同的影响,文中结合一座在建的城际铁路连续梁桥,通过建模数据分析不同合龙方案对主梁线形及力学性能的影响,以此优化采用挂篮施工的连续梁桥边跨合龙方案,为该类桥梁施工监控工作提供有益的参考。
The large-span continuous beam bridge constructed by hanging basket cantilever construction, the Helong section is the most important link in the construction process of the beam bridge. Different Helong construction schemes will have different effects on the bridge line shape and the main beam stress. The inter-city railway continuous beam bridge under construction analyzes the influence of different Helong schemes on the linear shape and mechanical properties of the main beam through modeling data, so as to optimize the continuous beam bridge side-span hoisting scheme with hanging basket construction, and monitor the construction of this type of bridgeand provide a useful reference for the construction monitoring of such bridges.
