摘要:
连盐铁路灌河特大桥主跨（120+228+120）m连续钢桁-柔性拱，为全线跨径最大桥梁。灌河特大桥的主桥糅合拱桥与下承式桁梁桥的双重桥梁造型，整体线型平顺、外形优美、配比和谐、受力合理。本文综合考虑桥位地质、通航、地震及台风等复杂条件，全面探讨了钢桁梁-柔性拱桥设计及施工中的主要工艺，并对主桥下部基础与围堰施工、钢桁梁同步拼装、主桥不对称悬拼与合龙、抗台风措施、新型TLMD双调谐阻尼器和主墩消能阻尼防撞系统等制造及施工新技术和新工艺作了说明。研究成果可为同类工程的设计和施工提供经验和借鉴。
Abstract:
Guanhe Super Major Bridge of Lianyungang-Yancheng High-speed Railway has a continuous steel truss-flexible arch main span of （120+228+120） m，the largest span among the bridges of the whole line. The main bridge of Guanhe Super Major Bridge is the combination of an arch bridge and an underlying truss girder bridge，featuring by smooth overall alignment，appealing look，harmonious proportion，and reasonable stress. This paper comprehensively discussed the main technologies in the design and construction of steel truss girder-flexible arch bridge，and explained the new manufacturing and construction technologies such as the construction of the lower foundation and cofferdam of the main bridge，the syn-chronous assembly of steel truss girder，the asymmetrical suspension and closure of the main bridge，the anti-typhoon mea-sures，the new TLMD double-tuned damper，and the energy dissipation damping anti-collision system of the main pier. The results can provide experience and reference for the design and construction of similar projects.
