| 摘 要： | 通过分析某花岗岩体场地地质环境条件，认为该场地地下坑道渗水主要受地形和断裂构造两个因子控制。利用ArcGIS地理信息系统软件基于地形数据提取了地表坡度、地表汇流累积量两个指标，基于地表构造填图提取了断裂密度指标，并分别生成专题图层。分别赋予这三个指标不同的权值，进行叠加运算，生成叠加图像用于评价某场地地下水富集情况，然后再根据富水断裂的产状来预测不同地段地下坑道的渗水可能性。现场调查验证表明，评价图具有较强的使用价值。

| Abstract: | By analyzing geological environmental condition of a granite site, it can be drawn that the geomorphy and the fracture are the most important factors that influence water permeation in tunnels. Using Arc GIS software system, slope and flow accumulation were extracted from geomorphy data,and fracture density from fracture data. A series of theme figures were generated based on these data. The water yield property in the site was obtained by overlay analysis with weight coefficients individually. Then the permeation possibility map of tunnels was forecasted according to the attitude of water bearing fault. Field investigation proved that the map is of considerable value. |
