Data Processing Model of GPS Dam Deformation Monitoring Network
Di Liu · Journal of Tongji University · 2007
In view of the particularity of the global positioning system(GPS) dam deformation monitoring network,a data processing model based on the station orthogonal coordinate system for three-dimension GPS dam deformation monitoring network is put forward.The paper also presents a mathematical model based on the clustering analysis method in fuzzy mathematics to test the relative stability of quasi-stable points(or datum points).The adjustment method during the course of data processing is quasi-stable adjustment.A software system of three-dimension GPS dam deformation monitoring network is designed and developed with the help of Visual Basic Language.With three periods' observation data from the GPS deformation monitoring network of a dam,an adjustment calculation is conducted by the software.The calculation result shows that the mathematical models can be more suitable for the data processing in GPS dam deformation monitoring network.
