Novel large-span arch combined pier structure and construction method
The invention discloses a novel large-span arch combined bridge pier structure, which comprises bridge pier stand columns and a bent cap arranged on the bridge pier stand columns, wherein the bridge pier stand columns are arranged at the two ends of the bent cap, and the bottom of each bridge pier stand column is provided with a pile foundation and a bearing platform; a main arch ring and a hanging rod are arranged on the bent cap, the main arch ring is of an arc-shaped structure with a downward opening, and arch feet of the main arch ring are arranged at the two opposite ends of the bent cap;the upper end of the hanging rod is connected with the main arch ring, and the lower end of the hanging rod is connected with the bent cap; and a main beam is arranged on the bent cap, and the positions of the hanging rod and the main beam do not interfere with each other. Compared with the prior art, an arch type system is adopted, multi-point elastic support is provided for the bent cap throughthe steel arch ring and the hanging rod, loads transmitted to the bent cap by the upper structure main beam are transmitted to the main arch ring through the hanging rod, the bending moment of the bent cap can be reduced, the rigidity of the bent cap can be improved, the span range of the bent cap can be greatly widened, the structural safety is high, and the applicability is wide.
一种新型大跨径拱门组合式桥墩结构，包括桥墩立柱和设置于桥墩立柱上的盖梁，桥墩立柱设置于盖梁的两端，桥墩立柱底部设有桩基和承台；所述盖梁上设有主拱圈和吊杆，主拱圈为开口朝下的弧形结构，且主拱圈的拱脚设置于盖梁的相对两端；所述吊杆上端与主拱圈相连，吊杆下端与盖梁相连；所述盖梁上设置有主梁，吊杆与主梁的位置互不干涉；与现有技术相比，采用拱式体系，通过钢拱圈和吊杆给盖梁提供多点弹性支撑，上部结构主梁传递给盖梁的荷载由吊杆传至主拱圈，可减小盖梁弯矩，提高盖梁刚度，可大幅提高盖梁的跨径范围，结构安全性高，适用性广。
