摘　　要：富民桥主桥为折线形双塔独柱式单索面预应力混凝土斜拉桥,针对该桥单索面、折线形塔的特点,通过运用能量法对成桥后塔柱的横向稳定问题进行分析,验证了结构设计的安全性。The main bridge of Fumin Bridge in Shenyang is a prestressed concrete cablestayed bridge with double kinked column pylons and single cable plane. In the light of the characteristics of the single cable plane and kinked pylons of the Bridge, the lateral buckling stability of the pylons at the completed bridge stage is analyzed by energy method, and the reliability of the structural design thereof is validated.
