Abstract


Deformation monitoring is an important means of monitoring the safety of deformation body , whose main task is to obtain deformation information through deformation monitoring , analysis and deformation information to make a judgment , the security situation of the deformable body . GPS technology as a new kind of cutting-edge technology has huge advantages compared with conventional measurement techniques , along with the constant improvement of the GPS system and the deepening of its research , GPS technology has become the main means of deformation monitoring . Outside the industry for deformation monitoring using GPS technology can reduce workload , improve work efficiency, so as to reap the maximum benefit . Therefore, the study of GPS technology for deformation monitoring and deformation data processing has important theoretical and practical significance . This paper discusses the GPS positioning theory based on the analysis of various error sources affect the accuracy of GPS deformation monitoring investigated , weakening or elimination of the way , summarizes the advantages and disadvantages of GPS deformation monitoring applications and monitoring mode; This paper also describes the technical design of the GPS deformation monitoring , focusing on GPS data processing and monitoring network adjustment , as well as multi - term monitoring data based unified . Subsequent prediction modeling of deformation monitoring data highlights the BP neural network forecasting model , and applied engineering instance , compare its predictive value and other commonly used forecasting model predicted values ??, and draw some practical conclusions .
