“…Centrifuge experiments performed by Abdoun et al (2003) on single piles and pile groups showed the axial forces in the pile group can lead to lower values of bending moments in the pile group as compared to a single pile. They postulate that the smaller moment demands in the pile group were due to the frame effect and the developed moment depended on the contribution of axial forces in the individual piles.…”

“…Most of the research focuses on the pile foundation, pile wharf, and so forth. For example, Takahashi et al [2] studied the seismic performance of pile wharf in the earthquake and analyzed the damage phenomena and failure mechanism of pile wharf caused by seismic permanent deformation; Abdoun et al [3] studied the dynamic response of the pile foundation in the earthquake by dynamic centrifuge model test; Jiao et al [4] analyzed the dynamic responses of the sheet pile wharf with separated relieving platform under horizontal seismic loadings; the Kobe and El Centro waves were taken to the numerical model, and it was found that the dynamic responses of the sheet pile wharf were affected by the dynamic characteristics, such as spectrum, wave energy density, and wave total energy.…”

Large deformation of slope caused by earthquake can lead to the loss of stability of slope and its retaining structures. At present, there have been some research achievements about the slope reinforcement of stabilizing piles. However, due to the complexity of the structural system, the coupling relationship between soil and pile is still not well understood. Hence it is of great necessity to study its dynamic characteristics further. In view of this, a numerical model was established by FLAC 3D in this paper, and the deformation and stress nephogram of sheet pile wall in peak ground motion acceleration (PGA) at 0.1 g, 0.2 g, and 0.4 g were obtained. Through the analysis, some conclusions were obtained. Firstly, based on the nephogram of motion characteristics and the positions of the slip surface and the retaining wall, the reinforced slope can be divided into 6 sections approximatively, namely, the sliding body parts of A, B, C, D, and E and the bedrock part F. Secondly, the deformation and stress distributions of slope reinforced by sheet pile wall were carefully studied. Based on the results of deformation calculation from time history analysis, the interaction force between structure and soil can be estimated by the difference of peak horizontal displacements, and the structure-soil coupling law under earthquake can be studied by this approach.

“…In order to fill in the necessary gaps, model studies are essential to predict the displacements, accelerations, and pore water pressures caused by a specified input motion. Researchers recently have been using large scale 1-g shaking table tests (He et al, 2006;Suzuki, Tokimatsu, Sato, & Abe, 2005;Tamura & Tokimatsu, 2005;Towhata, Sesov, Motamed, & Gonzalez, 2006;Thevanayagam et al, 2009) or the augmented gravity field centrifuge tests (Abdoun, Dobry, O'Rourke, & Goh, 2003;Arulanandan & Scott, 1993;Brandenberg, Boulanger, Kutter, & Chang, 2005;Dobry, Taboada, & Liu, 1995;Elgamal, Zeghal, Taboada, & Dobry, 1996;Haigh & Madabhushi, 2005) to study the behaviour of soil under more realistic seismic loading conditions. Both shaking table and centrifuge model tests have certain advantages and limitations.…”

In this paper, we focus on the development and performance of the 1-g model testing system to monitor the liquefaction occurrence of saturated soils, under subsequent one-dimensional shake table tests. The system is composed of one-dimensional laminar box, cone penetration system, soil model, system for hydraulic soil pumping to achieve loose soil deposit, instrumentation and associated testing hardware. In order to simulate the free-field conditions in the laboratory, the laminates slide on each other using rollers placed between each laminate. The static calibration test results demonstrate that the friction effects between the laminates and the rollers are satisfactorily low. The loosest and the most liquefiable sand deposit is prepared inside the laminar box by hydraulic filling process and subjected to four subsequent shaking tests at different intensities. First, the laminar box and shake table performance is verified by using time-histories of acceleration and displacement test results. Then, the measured data inside the soil and on the laminates are compared with the numerical model. The previously calibrated numerical model UBCSAND which shows the seismic loading conditions in the free field is used in the simulations. Those shake table test results and the numerical simulations of the box and the soil indicate that the usefulness of the laminar box system for shaking table tests is satisfactory for dynamic model tests in 1-g gravity.
