| 摘 要： | 将斜拉桥成桥后的误差调整问题归结为一个多目标、多约束的优化问题，并采用综合参数法进行求解，该方法的特点是通过凝聚函数将此问题转化为一个可微的单目标、单约束优化问题，在此基础上，采用乘子惩罚函数法进行求解，该优化方法不但适合成桥后的误差调整，同样适合斜拉桥施工过程中的误差调整。

| Abstract: | The error adjustment of cable-stayed bridge in finished state is considered as a problem of optimization with multi-objective and multi-constraint. Method of synthesized parameter is adopted to solve this question. The character of this method is to switch this question to an optimization of single-objective and single-constraint through aggregate function. The optimization is realized using a technique of multiplier penalty functions. The example proves the method is correct and feasible. This method is not only suit to error adjustment of bridge in finished state, but also suits to that of cable-stayed bridge in construction period. |
