摘要
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.
