| 摘 要： | 通过有限元软件中多种单元的尝试,得到了正交异性板桥面裂纹的夹芯板加固方法中夹心层的合理的有限元模拟方式,进而对正交异性板夹芯加固进行了有限元分析,得到了夹芯加固法的有效性,并对夹心层材料的弹性模量进行了参数化分析,得出了此参数对夹芯加固效果的影响,最终提出了合理的裂纹加固方案。

| Abstract: | This paper indicates a brief introduction of the sandwich plates method and its application.Using finite element software ANSYS and ABAQUS,several kinds of elements were compared to obtain a reasonable and economical finite element model,which is suitable for simulating the sandwich plates.Vehicle load was applied according to General Code for Design of Highway Bridges and Culverts.The sandwich plates method was proved effective through the analysis of non-strengthened and strengthened orthotropic steel bri... |
