摘要
通过理论分析与有限元软件模拟,研究了多跨一联大跨度连续梁桥临时约束的解除时机对结构受力及变形的影响,并根据计算结果进行分析,提出对类似桥梁施工的建议,以期使连续梁施工技术更加完善。
According to the theoretic analysis and simulation with the finite element software, the paper researches the influence of the relieving moment of the temporary constraints on the multi-span and single-linked large-span continuous beam bridge on its structural stress and deforma- tion, has the analysis according to the calculation results, and points out some suggestions for similar bridge construction, so as to perfect the con- struction technique of the continuous beam.
