Application Of Pressure-dispersion Anchor In Roadbed Slope

Slope reinforcement was a very important engineering technique. Therefore, the paper presents the stability analysis of slope at the site of Section B from K40+280 to K40+420 in Wanping expressway, furthermore it proposes a slope reinforcement method with compression dispersion-type anchor which has not glutinosity and concrete grid beam. On this base, the paper analyses the characteristic and the principle of high steep reinforcement of compression dispersion-type anchor, and designs a method which can make use of the compression dispersion-type anchor to reinforce the slope of Section B from K40+280 to K40+420 in Wanping expressway. Through observing the internal force of the compression dispersion-type anchor, it analyses the stability of the slope which reinforced with the compression dispersion-type anchor. The results indicate that the compression dispersion-type anchor is a useful technique for reinforcing slope. Finally, the paper presents the construction technique of this method on the base of engineering.
