Short cantilever simply supported rigid frame bridge with pull rods and construction method
The invention relates to a short cantilever simply supported rigid frame bridge with pull rods and a construction method. The short cantilever simply supported rigid frame bridge comprises a bridge abutment, bridge abutment supporting legs, variable-height beams, short cantilever beams and the prestress pull rods. The bridge abutment supporting legs are assembled on the bridge abutment, the variable-height beams are supported on the bridge abutment supporting legs, and the beam heights of the variable-height beams are gradually reduced from fulcrums to midspans; the short cantilever beams are connected with the variable-height beams; the prestress pull rods are connected with the short cantilever beams and the bridge abutment; the bridge is suitable for crossing roads, river channels and canyons, and a single-span bridge needs to be adopted due to the fact that the terrain is limited; with application of the bridge, one-span crossing can be achieved, and pier falling is not needed.
本发明涉及一种带拉杆的短悬臂简支刚构桥及施工方法，包括桥台、桥台支腿、变高梁、短悬臂梁和预应力拉杆；所述桥台支腿装配于桥台上，变高梁支撑在桥台支腿上，变高梁的梁高从支点向跨中逐渐变低；所述短悬臂梁与变高梁相连；所述预应力拉杆连接短悬臂梁和桥台；本发明适用于跨越公路、河道及峡谷，由于地形受限而需采用单跨的桥梁；采用本发明可实现一跨跨越而无需落墩。
