Visual Modeling Experiment of Soil Slopes Stabilized with Anchored Piles and Anchor Cable Frame Beams

Abstract:

A series of visual modeling experiments of soil slopes stabilized with anchored piles and anchor cable frame beams were conducted based on the transparent soil technology. Particle image velocimetry （PIV） was employed to investigate the displacement fields and failure processes of slopes at bar loading. The results show that anchored piles and anchor cable frame beams can enhance the ultimate bearing capacity of slopes. Its slip surface is deeper than that of an unreinforced slope. For the reinforcement of pushed landslides， the upper anchor cable works first. After it has been pulled out， the anchor cables that followed in turn exert effect until being pulled out. The stability of slopes stabilized with anchored piles and anchor frame beams is not conservative when the ultimate pullout resistance of all anchor cables is considered simultaneously as a component of the slip resistance. It is suggested that when checking the overall stability of the pushed landslide stabilized with anchored piles and anchor cable frame beams， the factor of safety of the uppermost anchor cable should be checked simultaneously to make it meet the factor of safety required by the project， thus ensuring the stability of the whole reinforced slope.
