Research on the Effect of Geocell in Slope Reinforcement Using Anti-Slide Pile with Geocell

Abstract

Geocell is a new type of geotechnical material, in order to illustrate its effect in slope reinforcement using anti-slide pile with it, the paper firstly establishes the calculation model of slope reinforcement using anti-slide pile with geocell. According to the elastic foundation beam theory, the paper analyses the force situation of geocell and its anti-sliding force calculation formula in slope reinforcement, at the same time, according to soil arch effect, anti-slide pile spacing calculation formula of slope reinforcement using anti-slide pile with geocell is established. Then through the finite element model, the paper compares no reinforcement, only using anti-slide pile with using anti-slide pile and geocell, from the result, we can conclude that the slope stability can be increased if we reinforce slope using anti-slide and geocell, when the slope stability coefficient is unchanged, if adding geocell, the pile spacing can be increased or the pile section can be decreased. So the investment can be saved in slope reinforcement.
