Comprehensive Analysis of Deformation Monitoring Benchmark Network Stability Considering Geographical Spatio-temporal Characteristics
摘要
Abstract
In order to effectively distinguish the causes of differences in the location of each network point during the remeasurement calculation of the deformation monitoring benchmark network,two or more testing methods are usually used to mutually support each other and weaken model errors.On the premise of confirming the reliability of observation data and the uniformity of adjustment benchmarks,we proposed a meth-od of using the limit test method combined with geographical spatio-temporal characteristics to comprehensively analyze the plane displacement of deformation monitoring benchmark network points for situations where t-test and/or average gap method couldn't be used to test the stability of point locations.Using engineering examples for analysis,it was initially determined that four network points were unstable.After gradual anal-ysis,it was ultimately determined that two of the points had experienced real displacement.The results show that the proposed method is simple,practical,and easy to understand and master.The comprehensive analysis conclusions of network point stability are in line with objective rules and approximate reality,which has reference significance for similar work in the future.关键词
