摘　　要：以自锚上承式拱桥———南京三山桥为工程背景,对此类桥型简化为平面模型的可行性进行了研究,并用实测数据进行了验证。同时依据自锚上承式拱桥的特性,提出了一种自锚预应力筋的设计方法,可供此类桥型设计时选用。Based on Nanjing Sanshan Bridge, a self- anchored deck arch bridge, its availability of simplified model for the kind of bridge is studied. According to the characteristics of self- anchored deck arch bridge, the design method of pre - stressed tendons arrangement is proposed, which might be used as a reference for this kind of bridge design in the future.
