摘　　要：三塔自锚式悬索桥作为一种新兴的自锚式悬索桥体系其在国内的建设方兴未艾。通过对该类桥型合理成桥状态的取得进行了原则和方法上的探讨,给出了一组确定合理成桥状态的具体步骤。同时以某实际工程桥梁为例,验证了该方法可行性,得到了较好结果。Self - anchored suspension bridges are increasingly welcomed by Chinese bridge engineers due to its anchor - block - free fee - reduction, adaptation to soft soil ground and unique aesthetic effects. The triple - tower self - anchored suspension bridge, as a brand new structural form, is just continuing its mass construction. Its principles and analysis methods were explored. Specific proce-dures were given to determine the reasonable finished dead load state and a practical project was used for verification of the method.

关 键 词：三塔自锚式悬索桥 合理成桥状态 吊索力优化
