南水北调配套工程石津干渠地质灾害危险性评估及防治措施

Risk Assessment of Geological Disasters and Prevention Measures of Shi-Jin Main Channel Construction in South-to-North Water Transfers Project

通过分析石津干渠建设项目特点及地质环境条件，对评估区范围内存在的各类地质灾害类型及特征进行了描述，并对其危险性进行了现状评估；对工程项目建设和运行过程中可能引发、加剧和遭受各类地质灾害的危险性进行了预测评估；在现状评估和预测评估的基础上，对地质灾害危险性进行综合评估，并对建设场地适宜性做出评估；针对建设项目可能遭受、引发或加剧的地质灾害，提出了具体的防治措施及建议。

This evaluation has analyzed features of Shi-Jin main channel construction project and its geological environment conditions. It has de- scribed types and characters of miscellaneous geological disasters in this region＇s assessing scope, and evaluated forecast fatalness existed. In addition, the assessment of any possible risks resulting in or even intensifying a geological disaster during engineering construction procedures and the implementation periods in the reservoir has also been carried out successfully in this area. On the basis of present-situation and predicted e- valuations, the whole appraisal has led an integrated assessment on the risk of geological disaster and evaluated the suitability of the construction site, thereby proposing concrete preventive measures and suggestions to avoid probable occurrences or aggravation of geological disasters in engineering procedure.
