| Description | Past earthquakes demonstrate that lateral spreading induced by liquefaction may cause excessive movement, and significant damage to structures and their underlying pile foundation. A 1-g shake-table series of experiments was conducted to investigate the mechanism of liquefaction-induced lateral spreading effects on pile foundations in mildly inclined ground. A single steel pipe pile of 25 cm diameter was tested under earthquake excitation in two different mildly inclined soil profiles of 2 and 4 degrees. The ground stratum was built of sand at about 1.8 m in height with a 1.1 m base saturated layer and an upper 0.7 m dry crust. For each inclination, data is employed to compare and assess peak pile response and soil behaviour pre- and post-liquefaction. Soil and pile lateral displacement as well as excess pore pressure are discussed. Such a pile-ground interaction mechanism is of consequence for analyses that correlate pile bending moments to the accumulated lateral soil deformation.

For each inclination, data is employed to compare and assess peak pile response and soil behaviour pre- and post-liquefaction. The pile represents a stiff behavior as evident from the large cyclic response then settling at zero displacement at the end. This indicates the soil flowing around the pile.
