整体式无缝桥梁桥台高度对主梁受力性能研究

Study on major beam stress performance of integral-seamless bridge abutment height

利用大型有限元软件ABAQUS,建立了整体式无缝桥梁全桥与台后土体及桩周土体相互作用的三维非线性有限元计算模型,分析了在砂类土地基中,不同桥台高度在自重及温度荷载作用下对整体式无缝桥梁主梁的受力影响,得出了一些有益的结论。

Applying large-scale finite element software ABAQUS , the paper establishes three-dimension nonlinear finite element calculation mode of mutual interaction among integral-seamless bridge abutment and post-abutment soil and soil surrounding the pile, analyzes the stress impact of different abutment height upon integral-seamless bridge beam under self-weight and temperature load action in sandy soil foundation, and finally draws some beneficial conclusions.
