摘　　要：针对超宽箱梁结构的细部受力情况以及结构参数的设计优化问题,对其研究现状进行分析。利用有限元分析法对箱梁腹板的内衬混凝土长度以及厚度参数进行分析优化。结果表明,内衬混凝土长度与中支点梁高比例为1.0时,混凝土厚度在20 cm以上时,箱梁腹板的力学性能最佳。In this paper,the research status of ultra-wide box girder structure is analyzed in terms of the detailed stress condition and the design and optimization of structural parameters.The length and thickness parameters of lining concrete of box girder web were analyzed and optimized by finite element analysis method.The results show that the mechanical properties of box girder web are the best when the ratio of lining concrete length to middle support beam height is 1.0 and the concrete thickness is above 20 cm.
