跨津秦客专80.6+128+80.6m连续梁临时支墩数值模拟计算

Numerical Simulation of the Temporary Pier of the 80.6+128+80.6m Continuous Beam Bridge on the Tianjin-Qinhuangdao Passenger Dedicated Line

以跨津秦客专跨径80.6+128+80.6m的连续梁临时支墩设计为例,对连续梁临时支墩的计算过程进行了详细的阐述,并通过有限元软件Midas对京津城际延伸线跨津秦客专特大桥的临时支墩进行了数值分析,结合施工现场的实际情况,说明有限元数值模拟方法满足施工现场要求。

Taking the design of the temporary pier of the 80.6＋128＋80.6m continuous beam bridge on the Tianjin-Qinhuangao passenger dedicated line as an example, the calculation process of the temporary pier of the continuous beam is analyzed in detail. Through the numerical analysis of the temporary pier of the bridge across Tianjin-Qinhuangao passenger dedicated line by the finite element software Midas, and combined with the actual conditions of the construction site, it is illustrated that this finite element numerical simulation method can meet the requirements of the construction site.
