摘要
针对扬水发电站沥青砂胶保护层劣化评价问题,在空间数据模型的构思下基于GIS平台功能,构建了整个评价系统。系统以数字照片为信息源,可以自动抽出由劣化产生的皱纹,计算其长度、面积等统计信息;对皱纹进行细化处理,计算其分形维数,以皱纹的统计信息和分形维数作为劣化度的评价指标。系统基于通用的COM技术开发,对于今后GIS在相关专业领域更深层次的应用具有一定的借鉴意义。
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.
