Slope Strengthening by Using a Grid Beam System

Abstract:

The evaluation of slope strengthening by using a grid beam system is carried out in this study by using a real slope existed in China is taken as the example to investigate the effects of the strengthening approach. The geological conditions of the example slope are introduced at first. The three dimensional element model of the slope is constructed with the aiding of the commercial package FLAC3D. The excavation process is simulated to obtain the stress distribution and displacement status. The slope performances without and with strengthening are numerical investigated and compared. The different bending moments of vertical beam of the frame and foundation pressure of slope reinforced with binding bolts, pre-pressed anchors and stress dispersion cables are computed. The made observations indicate that the stability of the slope has been obviously improved by applying the strengthening. The approach utilized in this study can also be adopted in the slope strengthening on the other sites.
