Abstract

Abstract

The data processing model based on station orthogonal coordinate system for 3D GPS highway subsidence monitoring network was analyzed and derived, a mathematical model based on clustering analysis method was put forward to test the relative stability of quasistable points(or datum points), and a quasistable adjustment method in the data processing course was proposed to compute minitoring data adjustments.A software system of data processing for the network was developed by using VC++, and the adjustments of three periods observation data of a highway subsidence from the network were computed by using the software.Calculation result shows that the middle square error of the plane coordinate is 1 mm, and the plumb one is 2 mm, so the mathematical model is more suitable for the data processing in the network.
