Abstract: The prerequisite condition of analyzing the procedure and tendency of slope deformation is to select reasonable monitoring point location.Due to the strong subjectivity of the existing monitoring point layout methods，the monitoring points are often misplaced and missed，and the deficiencies of single standard of point selection and low monitoring accuracy are obvious，which caused the overall monitoring effect is unsatisfactory，besides that，the current requirement of high precision slope deformation monitoring cannot be satisfied.In order to overcome the above deficiencies，a new slope deformation monitoring point optimal layout method based on the combination of sensitivity analysis with correlation analysis is proposed.The traditional point selection scheme by numerical simulation method is optimized from the aspects of precision and quantity.The north stope slope of Jinduicheng molybdenum open-pit mine in Shaanxi Province is taken as an example，the engineering application results show that the method proposed in this paper is a practical method，it not only can effectively enhance the reliability of deformation monitoring network，but also reduce the monitoring cost.
