摘要
由于库区的广域性和地质条件的复杂性,水库渗漏问题一直是水利水电工程中主要工程地质问题。近年来遥感技术、GIS(Geographic Information System,地理信息系统)技术、三维技术的发展,为水库渗漏分析提供了一个有力的工具平台。本文以某水库库区渗漏问题为研究对象,基于遥感技术、GIS技术、三维技术建立的三维遥感影像可视化系统,对某库区地形数据进行分析,结合地层岩性、地质构造、水动力条件等,辨识出库区可能渗漏通道,进行渗漏估算,判断库区水库渗漏情况。
Due to the geological complexity of the wide reservoir area,reservoir leakage problem has been the subject of research in water resources and hydropower engineering.In recent years,the development and application of GIS,remote sensing technology and three-dimensional(3D) technology have provided powerful tools in analyses of the reservoir leakage problem.Based on the 3D remote sensing image visualization system created with remote sensing technology,GIS and 3D technology,the leakage problem of a reservoir is examined.By analyzing the terrain data,the existing leaking channels are identified in combination with lithology,geological structure and hydrogeological conditions of the study area.The quantity of leakage is calculated to evaluate the reservoir leakage.With the characteristics of accuracy and timeliness,the system will play an important role in preliminary analyses of reservoir leakage problem as well as forecasting decision making.
