高速铁路CPⅢ平面控制网的优化设计

Optimum Design of CPⅢ Plane Control Network for High Speed Railway

采用模拟优化设计方法,对CPⅢ平面网的点位精度、相对点位精度和可靠性指标进行了分析,结果表明:标准CPⅢ平面网测量方案的可靠性指标较差,为此,提出了CPⅢ平面网的优化方案,采用本方案可减少CPⅢ网的复测次数。

By doing the simulation optimum design, the positional accurary,relative positional accurary and reliability of CPⅢ networks was analysed, and the result showed the reliability of CPⅢ network was bader. The optimum scheme of CPⅢ network was presented. And frequency of repeatable measurement of this CPⅢ network may was reduced.
