Research of Accuracy Improving in the Inter-City Railway Settlement Observation


Article Preview

This paper first introduces the inter-city railway settlement observation implementation scheme, and then makes a statistics analysis on the monitoring data of Wuhan to Xianning inter-city railway. The conclusion is as follow: the main factors that influence the precision of settlement observation are the misclosures of direct and reversed observations, if they are both at a certain range, all monitoring points’ mean square errors of height would reach 0.1mm. Finally summarizes some methods that can improve the precision of settlement observation, in the actual work they make very good effect.
