Abstract:The frame supporting structure with prestressed anchor for reinforcement of slope excavation is put forward. This technology has the advantages of convenient construction, and it can effectively improve the stability of high fill slope, and control the displacement and deformation of the slope. In order to better understand the reinforcement effect of the frame with prestressed anchor-plates, based on GeoStudio and the actual monitoring data, the displacement, deep horizontal displacement and stability of the high fill slope with and without anchor-plates are compared. The variation of axial force and soil pressure distribution of slope of anchorage section of anchor-plates are analyzed.
