摘　　要：结合某混凝土自锚式悬索桥工程,分析了该桥锚固区部位混凝土应力的分布特点及变化规律。根据计算结果,确定了主梁的合理施工方案,避免了混凝土主梁产生过大的拉应力,其计算结果及设计思路对同类工程有一定的参考价值。With reference to a self-anchored concrete suspension bridge, the distribution characteristics and varying laws of concrete stress at anchorage zone of the bridge are analyzed. In accordance with the calculation results, the reasonable construction scheme for the main girder of the bridge is determined and consequently the occurrence of excessive tensile stress in the concrete main girder is avoided. The calculation results and design considerations presented in the paper are of certain reference to the similar bridge works.
