| 摘 要： | 斜拉桥各架设几何形态与内力的确定是施行工程控制的重要前提。目前普遍采用的倒拆法数据量大，计算周期长、对大跨度斜拉桥更是如此。本文提出一种斜拉桥架设分析的新算法－－状态比较法。

| Abstract: | In this paper a new method state comparative method for the analysis of erection of cable stayed bridges is presented. Compared with the commonly used back remove method there exist some advantages of using this new method. By this method any stage of erection can be analyzed directly without any change of the topology and geometry of the computational model. Numerical example shows this method is correct and efficient. |
