福建立墩大桥系水口电站库区淹没公路改建工程跨越尤溪河的人工构造物,桥址距闽江汇合处约一公里。该桥为交通部“七五”期间重点科研项目,“用顶推法修建大于70米梁桥新技术的研究”的试验工点,是部公路科研所和福建省交通规划设计院共同设计的。不设临时墩,用顶推法修建大跨径梁桥,目前在我国最大的顶推跨径为50术,该桥最大跨径达76米。设计中有了不少新的尝试,可供参考。 Fuding Bridge Pier Department Shuikou Hydropower Station reservoir submerged highway reconstruction project across the Youxi River artificial structures, the bridge site from Minjiang confluence at about one kilometer. The bridge for the Ministry of Communications during the “75” key scientific research projects, “with the push law to build more than 70 meters beam bridge new technology research” test point, is the highway research institute and the Fujian Provincial Communications Planning and Design Institute jointly designed . There is no temporary pier and the long-span girder bridge is built with the push-in method. At present, the maximum push-in span in China is 50 and the maximum span of the bridge is up to 76 meters. There are many new designs in the design for reference.
