摘要: 以某电站进场道路上的连续刚构桥结构计算为工程背景,通过对该桥在特殊重载车辆下承载能力分析,并对不同荷载工况作用下,桥梁结构受压区高度变化进行了比较,提出了正截面抗弯承载力分析方法,为大件运输下连续刚构桥承载能力分析提供了参考作用。

Abstract: Taking the structural calculation on the continuous rigid frame bridge on the access road of a power station as the engineering background, through the analysis of the bearing capacity of the bridge under the special heavy load vehicles, and the comparison of the height changes of the compression zone on the bridge structure under different load conditions, the paper puts forward the analysis method on the bending bearing capacity of the normal section, which provides a reference for the bearing capacity analysis for the continuous rigid frame bridge under the transportation of large pieces.
