福平铁路大跨连续梁临时支墩数值模拟计算与分析

Numerical simulation and analysis of large span continuous beam temporary support pier in Fu-Ping railway

以福平铁路某80.6+128+80.6m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对某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,论证有限元数值模拟方法满足施工现场要求。

This paper takes a 80.6+128+80.6m continuous beam Fuping railway temporary pier design as an example, the continuous beam of temporary pier calculation process in detail, and the numerical analysis by the finite element software Midas temporary pier of a bridge, combined with the actual situation of the construction site, the fnite element the numerical simulation method can meet the requirements of construction site.
