摘　　要：自锚式悬索桥主缆锚固区是悬索桥设计的关键部位,对沈阳东塔跨浑河桥锚固区进行了局部精细化分析。通过对主缆拉力工况的分析,得到锚固区主要受力板件应力扩散情况,从应力云图中可见应力沿主要受力板件均匀扩散。通过对锚固区钢格构进行总体受力分析,确定了最优板件尺寸。The anchorage zone for main cable of self-anchored suspension bridge is the key part of suspension bridge design.The local fine analysis on the anchorage zone of Shenyang East Tower crossing Hunhe river bridge is made.The stress diffusion of the main stressed plates in the anchorage zone is obtained through the analysis on the tension condition of the main cable.It can be seen that the stress diffuses evenly along the main stressed plate from the stress cloud diagram.The optimal plate size is determined through the overall stress analysis of the steel lattice in the anchorage zone.
