高速公路施工临时钢栈桥施工计算

Calculation of temporary steel trestle construction for expressway construction

以实际工程为背景,对一贝雷梁钢栈桥进行施工计算,利用Midas Civil建立了空间三维模型,对结构进行了计算分析,结果表明,该贝雷梁钢栈桥的主梁、桥面板、下部结构的受力和变形均满足设计荷载工况的使用要求,结构的整体稳定性也满足要求。

This paper takes a practical engineering as the background and conducts construction calculations on a Bailey beam steel trestle bridge.Through Midas Civil established a three-dimensional spatial model and structure is calculated and analyzed.The results show that,it was found that the force and deformation of the main beam,bridge deck,and substructure of the Bailey beam steel trestle meet the requirements for the design load combination,and the overall stability of the structure also meets the requirements.
