Application of plastic concrete interlocking piles for slope seepage prevention in riprap foundation retaining engineering

Abstract

Based on the foundation pit support project at Shenzhen Shekou cruise center, the application of plastic concrete interlocking piles in slope seepage prevention in a riprap foundation support project near the sea was investigated via finite element analysis. From the characteristics of plastic concrete pile, the modulus of the same, elastic modulus of surrounding riprap foundation, diameter of pile, water level and other factors for slope stability, and influence of plastic concrete pile on slope stability and deformation was obtained. Based on the analysis, key suggestions on the anti-seepage characteristics of plastic concrete pile in slopes were made, and the anti-seepage application of plastic concrete pile in reclamation foundations in airports and power plants were prospected.
