淮北市地质花园地质灾害危险性评估

Hazard Assessment of Geological Hazard in Huaibei Geological Garden

以淮北市地质花园建设工程为例,对区内地质灾害现状进行了分析,并对工程建设引起的地质灾害危险性进行了预测评估。认为施工工程发生岩溶塌陷灾害的危害程度小,危险可能性也小。依据评估区的地质灾害种类,进行了危险性分区,将区内分为危险性大区、危险性中等区和危险性小区。在上述分析的基础上,分别就基坑边坡崩塌地质灾害防治措施和岩溶塌陷地质灾害防治措施进行了讨论,对于确保该区后续工程建设安全有一定的借鉴价值。

Taking the construction project of geological garden in Huaibei City as an example,the present situation of geological hazards in the area is analyzed,and the risk of geological hazards caused by the project construction is forecaseted and evaluated.It is considered that the hazard degree of karst collapse in construction project is small,and the hazard possibility is also small.According to the different types of geological hazards in the assessment area,the risk area is divided into three parts:the large risk area,the medium risk area and the small risk area.Based on the above analysis results,the measures for the prevention and control of the geological hazard of the slope collapse of foundation pit and the geological hazard of karst collapse are discussed respectively,so as to provide certain reference for ensuring the safety of the following project constrution in the area.
