摘要

摘要: 提出一种框架预应力锚托板加固技术,这种技术不仅施工方便快速,还可以有效提高高填方边坡的稳定性,并对边坡的位移和变形起到很好的控制作用。为了能够更好地了解框架预应力锚托板的加固效果,基于GeoStudio,结合实际监测数据,对比分析了有无锚托板时高填方边坡的坡肩位移、深层水平位移及稳定性,并对锚托板的锚固段轴力变化及边坡土压力分布规律进行了分析。

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.
