Abstract:Based on spatial data model on the GIS platform,an assessment system for asphalt mastic deterioration of water pumping storage power station is developed. The statistical information of wrinkles due to deterioration,such as length,area,etc.,can be extracted. After sophistication process of wrinkles,the fractal dimension can be calculated as a factor to assess the current deterioration condition. The system is implemented by the general technology of COM components between spatial data model and GIS,and could be a powerful tool for the other potential applications of GIS into rock mechanics for the different spatial analyses.
