Abstract: There are a lot of digging or filling soil slope need to be analysis and tracking in mountain construction project. The most directly factor impact on the slope stability and management measures is the site planning and the geological condition. We can control the project management and investment of the slope by reasonable site planning. Based on the study and analysis, construction of a slope project with complex geologic conditions. This paper elaborates the important role of site planning in the slope project, and the influence and restraint relationship between the two.
