摘要:
沪昆高速铁路跨越坝陵河大峡谷处拟设克地坝陵河特大桥，大桥设计中遭遇了桥址处复杂不良地质、桥位选择难度大、桥梁设计控制因素多、梁体和基础设计施工难度大等难题。经多方案比选，选取了较为合理的克地桥位方案，桥式方案采用大跨度预应力混凝土连续刚构。大跨度刚构具有经济合理、养护维修方便、养护工作量少、成本低等优点，在山区跨越深沟大壑或河流中被广泛采用。克地坝陵河特大桥结构构造合理，墩、梁线条简洁明快，与两岸陡峭地形相契合，充分发挥了连续刚构的结构优点。本文研究成果可为高速铁路大跨度刚构和高墩桥梁设计提供参考。
Abstract:
For the design of the Balinghe Super Major Bridge at Kedi where Shanghai-Kunming High-speed Railway crosses the Baling River Grand Canyon，many difficulties were encountered，such as complex and unfavorable geological condi-tions at the bridge site，difficulty in location selection，too many control factors for bridge design，and difficulty in design and construction of girder body and foundation. Through the comparison of multiple optional schemes，a more reasonable bridge location at Kedi was selected，and a long-span prestressed concrete continuous rigid frame was applied for the bridge structure. The large-span rigid frame has the advantages of economic rationality，convenient maintenance，less maintenance workload，and low cost，and is widely used for bridges crossing deep gullies or rivers in mountainous areas. The structure of Balinghe Super Major Bridge at Kedi is reasonable，and the lines of piers and girders are simple and forthright，which is in line with the steep terrain on both banks，giving full play to the structural advantages of continuous rigid frame. The results of this paper can provide a reference for the design of long-span rigid frame and high pier bridges of high-speed railways.
