摘要： 在系统调查主体工程的地质环境条件的基础上，运用赤平投影、量化评分等方法，对该拟建引水工程地质灾害的危险性进行评估，认为区内地质环境条件中等复杂，隧道进出口边坡与施工支洞段引发崩塌、滑坡、泥石流等地质灾害的可能性中等，82.9％为地质灾害危险性小区，适宜工程建设。针对可能引发或遭受的地质灾害，提出了相应的防治措施建议，为下一步工程建设和地灾防治提供参考。

Abstract: This paper presents geological hazards evaluation results for a water diversion project. Based the systematic investigation of the geological environments for the pivot structures, the hazard evaluation utilizes the stereographic projection and quantitative scoring methods. The results indicate that the project area has a medium complicated geological conditions, and the slopes at the aprons of the main diversion tunnel as well as the construction supporting tunnel have the medium probability of geological hazards, such as, rock collapses; slope instabilities and mudflows. Approximately 82.9% of the project areas have a low geological hazard rating and are suitable for the engineering projects. The mitigation approaches for the potential geological hazards are also proposed.
