摘要
目前,针对斜弯T梁桥横隔板布置的研究较少,为研究横隔板布置对桥梁力学性能的影响、优化斜弯桥横隔板布置,文章结合桥梁博士梁格模型,对不同横隔板道数、不同跨径及不同中隔板布置方式的正交、斜交桥梁开展受力分析.研究表明,25 m跨T梁布置2道隔板为宜,30 m、40 m跨T梁布置3道中横隔板为宜;对于正交、斜交桥梁,采用中隔板正布方式,受力性能均优于采用中隔板斜布.
Abstract
At present,there is little research on the arrangement of intermediate diaphragms for skew curved T-beam bridges.In order to study the influence of intermediate diaphragm arrangement on the mechanical properties of bridges and optimize the arrangement of intermediate diaphragms for skew curved bridges,this paper combines Dr.Bridge's grillage model to carry out stress analysis of orthogonal and skew bridges with different number of intermediate diaphragms,different spans and different intermediate diaphragm arrangements.The research shows that it is appropriate to arrange two diaphragms for 25 m span T-beam,and three middle intermediate diaphragms for 30 m and 40 m span T-beams.For orthogonal and skew bridges,the mechanical property of the normal arrangement of middle diaphragm is better than that of the oblique arrangement of middle diaphragm.
