摘要
以介休市一座大跨度连续刚构桥转体跨越铁路施工为研究对象,对该桥结构设计从基础尺寸、桥墩尺寸、梁部结构形式、施加顶力等方面进行了优化。优化后的矮墩连续刚构桥在8度地震下的受力更为合理,同时减轻了结构质量,降低了转体施工风险。
Taking the rotation construction of a large- span continuous rigid frame bridge across the railw ay in JiexiuC ity as research object, the structural design of the bridge w as optimized from the f low ing aspects, the foundationsize, the pier size, the structural form of girder and the application of the top force. T he optimized the continuous rigidframe bridge w ith short- pier is more reasonable under the eight degree earthquake, w hile the structural w eight andthe risk of rotation construction are reduced.
