Mountainous area rock anchor cable-stayed flexible arch cooperative system bridge and construction method thereof
The invention provides a mountainous area rock anchor cable-stayed flexible arch cooperative system bridge and a construction method thereof, and the mountainous area rock anchor cable-stayed flexible arch cooperative system bridge is applied to alpine and canyon areas, stretches across canyons and is erected between mountains on the two sides. A pile foundation is arranged on the mountain body on each side, the bridge towers are fixedly arranged on the pile foundations, one side, facing the mountain body, of the upper portion of each bridge tower is fixedly pulled by a plurality of rock anchors anchored in mountain body bedrock in a one-to-one correspondence mode through a plurality of inhaul cables, a plurality of sequentially-spliced section truss girders are hoisted on the other side of each bridge tower in a one-to-one correspondence mode through a plurality of stay cables, and the pulling force on the two sides of each bridge tower is balanced. The segment truss girders on the two sides are symmetrically arranged and connected through the micro-arch truss girders to form a complete main span, the concrete bridge deck is laid, and the micro-arch truss girders are of a flat and micro-arch truss girder structure. The novel large-span bridge structure system is suitable for mountainous and canyon areas, and is reasonable in stress, low in construction difficulty, economical, feasible and attractive in appearance.
本发明提供了一种山区岩锚斜拉柔拱协作体系桥，同时提出其施工方法，应用于高山峡谷地区，横跨峡谷、架设在两侧的山体之间；每侧山体上均是，设置有桩基础，桥塔固设在桩基础上，上部朝向山体的一侧通过多道拉索与锚固于山体基岩中的多个岩锚一一对应地相固定牵拉，另一侧通过多道斜拉索一一对应地吊起多段依次拼装的节段桁架梁，且两侧的拉力相平衡；两侧的节段桁架梁呈对称设置，之间通过微拱桁架梁相接，构成完整主跨，并铺设混凝土桥面板，微拱桁架梁呈扁平、微拱状桁架梁结构。本发明是一种适用于山区峡谷地区的新型大跨径桥梁结构体系，受力合理、施工难度低，经济可行、造型美观。
