Performance of sheet pile as a seismic retrofit for old piled abutment subjected to liquefaction-induced lateral spreading

Liquefaction-induced lateral spreading causes severe damage to the pile foundation of structures. Old structures that are not properly designed for liquefaction more vulnerable a strong earthquake. Many old piled abutments require remedial measure against spreading. This paper examines responses an abutment subjected liquefaction-induced and efficacy sheet reinforcement technique mitigate associated through dynamic centrifuge experiments. The experiment on reveals moves together with soil shows significant channel-ward movement without pinning effect. large bending moments found take place around head interface loose dense layer as expected. installation in front considerably reduces thus moment demand piles.
