Tianshan Highway (g217) Line Stability Evaluation, Route Selection Optimization Analysis System

DUShanzi-and-Kuche road is the national highway 217 important constituents, span 532km. For several dozens years, as a result of the special geography and the climatic conditions influence, this road are being called now by the national road "the road disease museum", the snow, the flood damage, the avalanche, the Debris flow, the frozen earth and so on road disease are here, the winter is at the condition every year which the transportation basically severs.Based on the ArcEngine platform, developing a set of collections foundations data gathering, the memory, the management, the retrieval,the graphic editor, the space model analysis, the line regionstability assessment, the highway alignment route selection as well as the three dimensional route flight achievement graph production and the output is a body "the Tianshan highway alignment stability appraisal and the route selection optimization analysis system(hereafter refers to as the Tianshan system). The Tianshan system collects the TianShan road's data including along the route to have the foundation geography and geology, the comparison field work achievement and the remote sensing achievement,carding on the corresponding synthesis, the reorganization,the induction and the transformation according to the database rule, and establishes data platform foundation geography-database, geological disaster database and so on by using ArcGIS, providing the data-support for the line region stability appraisal-analysis as well as the road route selection decision system.The main paper characteristic manifests in following several points:(1) Based on newest GIS module ArcEngine, the union engineering geology application model and the mathematical formula, carries on the system the skeleton, fully manifests "the GIS+ specialty" design mentality.(2) Through the selection index system and the stable appraisal method model, carries on the line geology disaster-risk appraisal to the Tianshan road, gaining the risky evolution map,at the same time this evolution map also is one of road routes-election factors, achieving two organic synthesis.(3) Dynamic segment technology as well as spatial database version-management technology application.
