A RESEARCH ON DATA PROCESSING MODEL OF GPS DAMDEFORMATION MONITORING NETWORK

摘要

Considering the particularity of the GPS dam deformation monitoring network, a datarnprocessing model based on the station orthogonal coordinate system for three-dimension GPSrndam deformation monitoring network, was put forward. Also, a mathematical model of using thernclustering analysis method in fuzzy mathematics to test the relative stability of quasi-stablernpoints(or datum marks) was successfully brought forward. The adjustment method during therncourse of data processing was quasi-stable adjustment. At last, a software system ofrnthree-dimension GPS dam deformation monitoring network was designed and opened up withrnthe help of Visual Basic Language. With three periods’ observation data from the GPSrndeformation monitoring network of a dam, an adjustment calculation was done by the software.rnThe calculation result shows that the mathematical models can be more suitable for the datarnprocessing in GPS dam deformation monitoring network.
