摘　　要：以浙江嘉兴某快速路项目为依托,通过Y形墩不同分叉角度和分叉部分墩高情况下的墩柱应力情况分析,探究各参数对Y形墩受力影响。在此基础上进一步提出针对Y形墩受力的最优设计准则,确定最优受力状态的Y形墩设计方案,为以后同类型桥梁下部结构的设计和研究提供参考。Based on an expressway project in Jiaxing, Zhejiang Province, the influence of various parameters on the stress of Y-shaped pier is explored through the analysis of the pier column stress under the conditions of different bifurcation angles and bifurcation part pier heights. On this basis, the optimal design criteria for the stress of Y-shaped pier is further proposed and the design scheme of Y-shaped pier under the optimal stress state is determined, which provides a reference for the design and research of the substructure of the same type of bridges in the future.
