Comparative Study on the Anti Sliding Performance of Circular and Rectangular Cross-section Anti-Sliding Piles

Abstract

Anti-slide pile is a retaining structure commonly used in large-scale landslide reinforcement. It usually adopts large cross-section rectangle pile by artificial excavation, but the defects of this pile are long work cycle, large excavation disturbances and personnel safety of builders in hole can't get effective guarantee in the rainy season and stratum saturated by water. However, the circle section pile has advantages of applying rotary pile drill into holes, high efficiency pore-forming, small excavation disturbances, and the option of aperture convenient and flexible. The circle section pile has obvious superiority to large cross-section rectangle pile. But the mechanism and design calculation of anti-slide pile group with the space frame structure of circle section has not the existing specification to adopt. This study aims to contrast and discuss the anti-sliding effectiveness between circle and rectangle section anti-pile through experiment.
