【 摘 要 】

To reveal the long-term evolution law of the Loess Cutting Slope in the process of construction and operation, A typical loess cutting slope in is selected as the research object, and the numerical analysis and field monitoring is adopted. Layout of monitoring sections, the subgrade settlement and lateral displacement of the slope as the main monitoring parameters, which the deformation rule of slope for long-term is monitored. The stability of the slope before and after the excavation is compared and analyzed. The monitoring data and analysis results guide the construction of loess slope well, and reveal the deformation and evolution law of the loess slope.
