摘要:
泸定大渡河兴康特大桥是雅康高速公路上的控制性工程,桥址区域为高海拔山区深切峡谷地貌,地形地质条件复杂、地震烈度高。设计者从桥位选择、桥跨结构布置、桥梁抗震设计等方面做了充分的方案比选论证和切实可行的技术创新。桥位选择采用趋利避害的设计理念、雅安岸隧道锚与邻近公路隧道间的协调布置方案,以及铰接式耗能型中央扣和波形钢腹板桥塔横梁结构在大桥上的创新应用,为复杂艰巨山区及高烈度强地震区修建大跨径悬索桥提供了较为丰富的设计新思路和新理念,值得工程界借鉴参考。
Abstract:
Xingkang Dadu River Bridge in Luding is the key project of Sichuan Yakang Expressway.The bridge site is a deepcut canyon in highaltitude mountain area.The terrain and geological conditions are complex,and the earthquake intensity is high. Design engineers have made sufficient scheme comparison and practical and feasible technological innovation,including bridge location selection,structure layout and seismic design. The selection of bridge location abides by the design concept of seeking benefits and avoiding disadvantages. The arrangement of tunnelanchorage on Ya’an bank is coordinated with the adjacent highway tunnels in the structural space. Some new design ideas are innovatively applied in the bridge,such as the articulated energydissipating central buckle the steelconcrete composite cross beams with corrugated steel webs used on the bridge towers. This project provides new design ideas and concepts for the construction of longspan suspension bridges in complex and arduous mountain area and highintensity seismic region, which is worthy to be refered to by engineering.
