| 摘 要： | 陕西省引汉济渭工程跨越秦岭构造剥蚀山地和断陷盆地,地质环境条件差,发育地质灾害点72处。选取地质环境条件、地质灾害发育现状和地质灾害预测为评价指标,分别赋予隶属度值;将工程剖分为284个评价单元,采用模糊数学综合评判法计算每个单元的隶属度值,确定危险性小的单元255个,危险性中等的单元29个;说明工程主要位于危险性小的区段。

| Abstract: | Hanjiang-to-Weihe River Diversion Project is constituted by 5 units of hydraulic power engineering construction in shaan＇xi province.As traversing denuded Qinling mountain and fault basin,the engineering geology conditions are complex and varied.Based on field surveyed,there are 72 geological hazards.Taking the engineering geology conditions,present geological disaster situation and prediction as the evaluation indexes,degrees are given respectively.The projection is divided into 284 units to be calculated by the method of Fuzzy Mathematics,and 255 units are low degrees and 29 are medium.The project will face low risk. |
