摘要
【目的】晋祠鱼沼飞梁作为“世界上最古老的立交桥”,凸显着山西古建筑的文化特色。【方法】通过回弹仪对晋祠鱼沼飞梁石柱抗压强度进行测试;依据测绘图纸利用AutoCAD软件进行三维建模,并利用ABAQUS有限元分析软件对其静力荷载及地震作用下的整体稳定性进行数值模拟分析。【结果】结果表明:鱼沼飞梁在静力作用下,构件所受应力远小于允许值,地基沉降量较小,趋于稳定;在地震作用下,结构受力均匀对称,顶面位移最大,石柱第三主应力主要集中于柱脚与柱顶,且沿地震波加载方向,斜截面发展,所受应力也小于允许值,具备较好的抗震稳定性。本研究可为鱼沼飞梁日后的保护和修缮工作提供参考依据。
【Purposes】As the"world's oldest overpass",the Flying Bridge across Fish Ponds in Jinci Temple highlights the cultural characteristics of ancient buildings in Shanxi.【Methods】In this paper,the compressive strength of the stone pillars of the Flying Bridge across Fish Ponds in Jinci Temple was tested with the rebound meter.AutoCAD software was used for three-dimensional mod⁃eling according to the mapping paper,and Abaqus finite element analysis software was used to simu⁃late and analyze the overall stability under static load and seismic action.【Findings】The results show that under static action,for the Flying Bridge across Fish Ponds,the stress of the components is much less than the allowable value,and the settlement of the foundation is small and tends to be sta⁃ble.Under the action of earthquake,the structural force is uniform and symmetrical,the top surface displacement is the largest,the third main stress of the stone column is mainly concentrated on the foot and the top of the column,and along the seismic wave loading direction,the oblique section de⁃velops,the stress is also less than the allowable value,and has good seismic stability.The results of this work can provide a reference for future conservation work of the Flying Bridge across Fish Ponds.
