上海市某地下通道工程地质灾害危险性评估

The hazardous evaluation of the geological disasters at some underground channel project in Shanghai

以上海市某地下通道工程为背景,首先对评估区已有地质灾害的类型、规模、危害对象进行了现状评估,通过分析工程建设和地质环境的相互作用,对工程建设过程中引发或加剧地质灾害的可能性和工程本身遭受地质灾害的危险性,进行了地质灾害危险性预测评估,并以此对评估区进行地质灾害危险性分区、分级综合评估,根据综合评估结果,提出地质灾害防治对策措施。

In this paper,the underground tunnel project in Shanghai as the background,this paper has assessed the situation of the area known type,the size and the object hazard of geological disasters and has analyzed the interaction between construction and geological environment,it assessed the geological hazard forecasting,including the construction process caused or exacerbated by the possibility of geological disasters and the project itself suffered geological disaster risk assessment,and it carried out the geological hazard assessment and comprehensive assessment and geological hazard area zoning,classification,according to the comprehensive assessment results,this paper has presented the geological disaster prevention countermeasures.
