水准网最弱点精度评估的方法研究

水准网最弱点精度评估是水准网性能的一个重要指标,前期水准网设计阶段必须进行最弱点精度评估并辅助调整网型设计. 由于设计阶段无具体观测数据,传统平差软件无法进行评估,因此本论文在间接平差的理论基础上结合测区经验,提出新的最弱点精度评估方法,并基于matlab进行最弱点精度评估程序设计且进行实例运用,验证了此评估方法的可行性,对类似工程具有一定的参考价值.

The Research of Method to Evaluate the Weakest Point's Precision in Leveling Network

The weakest points' precision assessment is an important index for leveling network performance , to eval-uate the most weakness precision is essential during leveling network design phase .While traditional adjustment software cannot evaluate precision when there is no specific observation data during design phase , so this paper put forward the most weakness precision evaluation method on the basis of the theory of indirect adjustment combining with the experi -ence test area , also produced the most weakness accuracy assessment programming on MATLAB and made an example . The result indicates that this evaluation method is feasible and has certain reference value to similar projects .
