The Effect of Fixed Piles Tip on Stabilization of Earth Slopes

Abstract

A recent widely researched solution is slope stabilization using a row of piles. In this study, the effects of fixed-tip pile and the subsequent pile length reduction, which finally bring about a reduction in stabilization costs were considered. This paper, presents novel analyses that were carried out in static condition. The analyses were performed using the limit equilibrium (LE) method and shear strength reduction (SSR) method, which approve of one another. Fixing pile tip was an efficient and applicable method for stabilizing earth slopes and reducing pile length.Results of these analyses were acceptable and were properly consistent with the results obtained by other researchers. The process of fixing end of pile were also carried out experimentally, and a new method proposed for this purpose, besides its simplicity, is cost effective and practical.The result of this investigation shows the effectiveness of the proposed method, in which, fixing the pile tip could enhance factor of safety (FOS) up to 55 percent.

Limit Analysis, Numerical and Physical Modelling of Pile Stabilized Slopes

“…For this purpose, a series of experimental modeling performs on sandy slopes, and they investigated failure conditions in the slopes by using the arti cial load method and seepage. Lee et al [31], Shara and Sojoudi [32], Hajiazizi et al [33], and Mazaheri [33] have been studied the effect of slope stabilization on the concrete pile.…”
