中文摘要：

结合铁路钢箱混合梁斜拉桥实际工程，利用大型有限元计算软件ANSYS对混合梁钢-混结合段的受力状态开展有限元分析，通过计算得到结合段模型在最不利荷载组合工况下的应力分布和变形情况。计算结果表明，钢-混结合段的钢板和混凝土的受力状态均处于安全设计范围之内，传力顺畅，受力合理。

英文摘要：

According to project example of hybrid girder cable-stayed bridge in railway engineering, the finite element program ANSYS is used to analyze the mechanical properties of steel and concrete joint part. We can get the stress and deformation state of the joint part under the least favorable condition. The results show that the mechanical state of steel and concrete in the joint part are within the scope of the safety design, in which the load transfers well.
