Abstract

A series of shake table tests is carried out on the lateral flow of the ground due to soil liquefaction during earthquakes. The model grounds are 6.0 m long, 0.8 m wide and their average height is 1.2 m. The slope of the ground surface and the lower boundary condition of liquefiable layer are varied, and the sinusoidal accelerations with a frequency of 2 Hz are inputted for 20 seconds. The deformation of model grounds, the excess pore water pressure of the liquefied layer, and the acceleration of the grounds are monitored. Based on the test results, the influence of the slope, the input motion and the thickness of liquefied layer to the ground flow is examined, and the fundamental characteristics of lateral ground flow induced by soil liquefaction are clarified experimentally.

Experimental Study on Lateral Flow of Ground Due to Soil Liquefaction

St. Louis, Missouri

A series of shake table tests is carried out on the lateral flow of the ground due to soil liquefaction during earthquakes. The model grounds are 6.0 m long, 0.8 m wide and their average height is 1.2 m. The slope of the ground surface and the lower boundary condition of liquefiable layer are varied, and the sinusoidal accelerations with a frequency of 2 Hz are inputted for 20 seconds. The deformation of model grounds, the excess pore water pressure of the liquefied layer, and the acceleration of the grounds are monitored. Based on the test results, the influence of the slope, the input motion and the thickness of liquefied layer to the ground flow is examined, and the fundamental characteristics of lateral ground flow induced by soil liquefaction are clarified experimentally.
