蝴蝶型拱桥稳定性参数分析
Parameter analysis on the stability of butterfly shape arch bridge
摘要
Abstract
Based on the finite element model of real bridge,the stability of butterfly shape arch bridge is analyzed using the parameters including different loads,rise to span ratios,inclined angles and link displacements.The results show the optimal inclined angle and rise to span ratio would be selected to obtain the best stability of the structure.The link between main arch rib and vise arch rib located at the mid-span has most influence on the stability,and the stiffness of the main arch rib is recognized as a critical element for increasing the stability of the bridge.关键词
