Analysis of Slope Excavation Deformation and Stability Under Different Excavation Stages
The excavation stage of slope is a common consideration in the actual project, which has a certain impact on the stability and deformation of the slope. Based on this, taking the soil-rock dual slope of a highway in Guizhou as the research background, the finite difference method is applied to simulate the whole process of slope excavation and the validity of the numerical simulation is verified by comparing with the field monitoring data. The influence of excavation stages on slope displacement field and stability factor of safety is further discussed. The results show that increasing the number of stages can effectively improve the stability and reduce the displacement value during slope excavation. However, after the excavation is completed, there is no significant difference in the stability and displacement of the slope under different excavation stages. It is recommended to increase the number of excavation stages reasonably and appropriately when excavating slopes to ensure excavation stability and reduce the amount of displacement. The relevant research can provide a useful reference for the construction stability analysis, monitoring and design of similar slope projects.
