Abstract

The purpose of this test was to realistically reproduce soil liquefaction and the lateral spreading of saturated sand deposits behind the sheet-pile quay walls and the consequent deformation and translation of neighboring pile foundations. Therefore, a shake table test was carried out using a large-scale laminar box on the large-scale shake table in Tsukuba. The inside dimensions of the model were 11.6 m in length, 3.1 m in width and 4.5 m in depth. Next, a dynamic centrifuge test on the behavior of a sheet-pile wall and a soil pile system was conducted to simulate that of a large-scale shake table test as a prototype. The shake table test was performed under a centrifuge acceleration of 15g. The large-scale test results showed that the lateral displacement of the sheet-pile is increased by about 5 seconds during the shaking, while the sheet-pile showed significant lateral spreading for about 200 seconds after the shaking. The centrifuge study generally confirmed that it is possible to simulate a large-scale test for lateral spreading of a sheet-pile wall and its backfill.

Large-Scale Shake Table Test on Lateral Spreading of a Sheet-Pile Wall Model and Its Centrifuge Simulation

San Diego, California

The purpose of this test was to realistically reproduce soil liquefaction and the lateral spreading of saturated sand deposits behind the sheet-pile quay walls and the consequent deformation and translation of neighboring pile foundations.

Next, a dynamic centrifuge test on the behavior of a sheet-pile wall and a soil pile system was conducted to simulate that of a large-scale shake table test as a prototype. The shake table test was performed under a centrifuge acceleration of 15g. The large-scale test results showed that the lateral displacement of the sheet-pile is increased by about 5 seconds during the shaking, while the sheet-pile showed significant lateral spreading for about 200 seconds after the shaking.
