Abstract: 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.
