摘要
通过对附合水准路线误差特点的分析,构建了附合水准路线平差的优化模型。提出附合水准路线的蚁群智能平差方法,建立了附合水准路线平差的蚁群可行解的搜索方案和蚁群行进策略。通过采用精英保留策略,加速了附合水准路线的平差进程。通过工程案例,证实了附合水准路线的蚁群智能平差方法可行且有效,并且发现采用附合水准路线的蚁群智能平差方法的精度明显高于采用经典平差方法的。
Through the analysis about the characteristics of error in annexed leveling, the adjustment calculation model was established.The paper presented a new method about adjustment calculation of annexed leveling which is based on ant colony algorithm. In this method, the searching scheme of feasible solutions is designed based on ACO,moving strategy of ants.The method facilitated the analyzing and calculation procedures by the elitism strategy.At last, through engineering examples, this paper confirmed that the method about adjustment calculation of annexed leveling based on ant colony algorithm was affected.Furthermore, the adjustment calculation accuracy of annexed leveling based on ant colony algorithm was significantly higher than adjustment calculation by the classical method.
