摘　　要：为解决长昆客运专线斜跨潭韶高速公路的问题,通过桥式方案比选,结构构造优化,结构静力、动力计算分析,设计研究出拱肋沿桥轴线非对称错位布置、吊杆扇形布设、无风撑拱肋的中承式斜置拱桥。该桥已投入实际运营,应用良好。To resolve the problem in design to allow Changsha-Kunming passenger dedicated railway to cross over Xiangtan-Shaoshan highway, this paper, on the basis of bridge scheme comparison, construction structure optimization, calculation and analysis of structural statistics and dynamics, comes to the conclusion that the half-through anomalistic arch bridge is recommended and arranged unsymmetrically and misplaced with its arch ribs along the bridge axial line, with its suspenders placed in fan-shape and its arch ribs without wind bracing. This bridge has been put into use with good results.
