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。
On the basis of systematically investigating the geological and environmental conditions of the main project, the authors use the methods of red-projection, quantitative grading and other methods to evaluate the risk of geological disasters of the proposed diversion project. The geological conditions in the area are medium and complex, and the entrance and exit sideslope With the possibility of geological disasters such as collapse, landslide and debris flow caused by the construction of the branch hole, 82.9% of them are dangerous areas with geological disasters, and are suitable for the construction of the project. In view of the geological disasters that may be caused or suffered, some suggestions on prevention and control measures are put forward to provide references for the next step of project construction and disaster prevention.
