Study on Anti-Slide Pile Spacing in Slope Reinforcement Using Anti-Slide Pile with Geocell and Influencing Factors

Abstract

Anti-slide pile spacing is a very important parameter in slope reinforcement engineering, it affects investment of the reinforcement engineering and slope safety. In order to determine reasonable pile spacing, this paper 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. The paper analyses the effect of geocell height, depth and length on anti-slide pile spacing. It is concluded that geocell length has the largest effect on anti-slide pile spacing, depth is the second and height almost has no effect.
