High-speed railway long-span bridge abutment and construction method thereof
The invention provides a high-speed railway long-span bridge abutment and a construction method thereof, and relates to the technical field of bridge engineering.The high-speed railway long-span bridge abutment is used for connecting a bridge and a tunnel and comprises an abutment body and an abutment tail wing plate, the abutment body comprises an abutment body, a top cap and an abutment top, and the abutment top is arranged on the abutment body; the top cap is connected with the lower portion of the end, close to the bridge, of the abutment body and used for supporting the bridge, and the abutment tail wing plate is connected with the end, close to the tunnel, of the abutment top and used for being inserted into the tunnel. According to the scheme, the abutment body is shortened, the size of the abutment body is reduced, and the excavation volume and disturbance to a bank slope are reduced, meanwhile, the abutment tail wing plate on one side of the abutment body is inserted into the tunnel, stable transition connection between the large-span abutment and the tunnel is achieved, and due to the fact that the thickness of the abutment tail wing plate is smaller than that of a bridge, the large-span abutment can be stably connected. When the tunnel is inserted, the increment of the section of the tunnel entrance end is small, the transition amount of the section of the tunnel entrance end and other sections is small, and the transition difficulty is small.
本发明提供了一种高速铁路大跨度桥梁桥台及其施工方法，涉及桥梁工程技术领域，所述高速铁路大跨度桥梁桥台用于连接桥梁与隧道，包括桥台本体及台尾翼板，桥台本体包括台身、顶帽及台顶，台顶设于台身上，顶帽与台身靠近桥梁的一端的下部连接，顶帽用于支撑桥梁，台尾翼板与台顶靠近隧道的一端连接，台尾翼板用于插入隧道。本发明方案，在将桥台本体做短，减少桥台本体的体积，减少对岸坡的开挖量和扰动的同时，利用桥台本体一侧的台尾翼板插入隧道，实现大跨度桥台与隧道的平稳过渡连接，且由于台尾翼板相较于桥梁而言厚度较小，插入隧道时隧道入口端断面的增加量较小，隧道入口端断面与其他部分断面的过渡量小，过渡难度小。
