摘　　要：建设项目地质灾害危险性评估是工程建设中的一项重要基础性工作,合理确定建设项目的地质灾害危险程度对确保工程安全有着重要意义,同时也对社会经济发展产生重大影响。运用AHP信息量层次分析法将文昌木兰湾新区建设项目评估区划分为441个单元,建立地质灾害危险性评估体系,将该评估区地质灾害危险性程度分为中、小2个等级,并根据划分等级进行地质灾害危险性分区。预测分析该评估区地质灾害危险性中等区和小区在工程建设时引发或加剧和遭受地质灾害危害的可能性以及危险性程度,并针对相应的可能存在危险性区域提出了不同的防治建议。Geological disaster risk assessment of construction projects is an important basic work in engineering construction.Reasonable determination of the geological disaster risk degree of construction projects is of great significance to ensure engineering safety,and also has a significant impact on social and economic development.The assessment zones were divided into 441 units by AHP,and the geological disaster assessment system was established.The geological disaster assessment zones were divided into two grades:medium and small,and the geological disaster zones were divided according to the grades.In this paper,the possibility and risk degree of geological disaster caused or aggravated and suffered by geological disaster are forecasted and analyzed,and different prevention and control suggestions are put forward according to the corresponding potential hazard areas.
