The Deformation Monitoring is an important work in the construction of high-speed railway passenger line , the data and information provided by the deformation monitoring , warning and forecasts , can prevent the unnecessary destruction and loss of engineering and social . Passenger Dedicated high-speed rail deformation monitoring cycle is long , high- frequency , will be tens of thousands of observation points , the data obtained from these observations point if the use of artificial methods for calculation , analysis, forecasting , and almost impossible to achieve . In addition, with the rapid development of network technology , the Internet has increasingly become the default platform for applications and GIS development , B / S architecture has become the best choice to build the application . RIA is a similar to the features and functionality of traditional desktop applications , network applications , has irreplaceable advantages in terms of interface expressive and interactive capabilities , network transmission . Web GIS applications GIS real service to the community , for the wider social groups . Therefore, the development of high-speed railway passenger dedicated line deformation monitoring and early warning system , combined with the advantages of RIA technology and web GIS technology Passenger Line the deformation monitoring online data processing , analysis , early warning, management function has a very important significance . Based on the above analysis , the paper first go into the details to ensure quality control of the deformation monitoring data , the classification of existing assessment indicators and improved methods , the applicability of the prediction model and the method of selection of the optimal model , as well as superimposed region smooth settlement Passenger Line assessment methods . Concluded from an evaluation perspective on this basis, be able to play a warning and forecasting role in the the Passenger Dedicated deformation monitoring and early warning system of early warning indicators . Second , ensure data quality and reliable assessment of the analytical methods RIA ( rich Internet applications ) and the Web GIS achieve key technology Silverlight , Bing Maps , the Web service and database management technology and propose how to build Silverlight-RIA - based technology Passenger Line deformation monitoring and early warning system implementations , and according to the needs of the system , the overall design, functional design , and database design . Finally , through the realization of the Passenger Dedicated deformation monitoring and early warning management prototype system to verify the feasibility of the key technologies and technical solutions .
