摘　　要：斜拉桥索塔锚固区的受力十分复杂,通过索塔锚固区的足尺模型试验,并进行空间的有限元分析,给出空间分析的一些主要成果及与试验实测值的比较,得出了许多重要结论。试验结果对沈阳市富民桥的建设有重要的指导作用。The stress distribution in a stay cable anchorage zone in cable-stayed bridge pylon is normally very complex. Based on the full-scale model test and spatial finite element analysis of the anchorage zones of Fumin Bridge in Shenyang, the values obtained from the spatial analysis and test results are compared, and some important conclusions are drawn. ＂The results herewith may be served as the important guidance to the construction of Fumin Bridge.
