【摘要】 针对峡谷河流两岸原有公路需修建曲线形桥梁解决车辆转弯过河的问题，提出双曲线形桥面的山坡锚固悬索和斜拉索混合索桥方案。双曲线形桥面交通流畅，山坡锚固的筒网状悬索网悬吊左、右2幅双曲线形加劲梁的内侧，山坡锚固的空间曲面斜拉索网斜拉左、右2幅双曲线形加劲梁的外侧，结构简明。结合某400 m超大跨径的峡谷河流双曲线桥梁工程，进行几何构形研究，建立midas有限元计算模型，开展竖向荷载和动力模态特性分析。更多还原

【Abstract】 In view of the need to build curved bridges for the original roads on both sides of the canyon and river to solve the problem of vehicles turning and crossing the river, a design scheme of a hyperbolic bridge deck hybrid cable bridge with hillside anchored suspension and stay cables is proposed. The traffic on the hyperboloid bridge deck is smooth. The bridge structure is concise, and inside and outside of the left and right hyperboloid stiffening beams are respectively suspended by the cylindrical mesh suspension network and the spatial curved cable network, which are both anchored on the hillside. Combined with a 400 m super-span canyon river hyperbolic bridge project, the geometric configuration research is carried out, the Midas finite element calculation model is established, and the vertical load and dynamic modal characteristics are analyzed.更多还原
