“…In recent years, the shaking table has continued to be widely used to study the seismic response of various types of structures. Matsuo et al (1998) researched the dynamic response and failure modes of geosynthetic reinforced soil retaining walls by using a large-scale shaking table. Ling et al (2005) presented an experimental study on the dynamic performance of modular-block reinforced soil retaining walls backfilled with sand.…”

A large-scale shaking table test was performed to study the dynamic response of slopes parallel to geological bedding (bedding slopes) and slopes that cross-cut geological bedding (counter-bedding slopes). The test results show that the acceleration amplification coefficients increase with increasing elevation and, when the input earthquake amplitude is greater than 0.3 g, both bedding and counter-bedding slopes begin to show nonlinear dynamic response characteristics. With increasing elevation, the displacement of the bedding slope surface increases greatly. Conversely, the displacement of the counter-bedding slope surface increases first and then decreases; the slope develops a bulge at the relative elevation of 0.85. The displacement of the bedding slope surface is greater than that of the counter-bedding slope. The counter-bedding slope is more seismically stable compared with the bedding slope. Based on the Hilbert-Huang transform and marginal spectrum theories, the processes that develop dynamic damage of the bedding and counter-bedding slopes are identified. It is shown that the dynamic failure mode of the bedding slope is mainly represented by vertical tensile cracks at the rear of the slope, bedding slide of the strata along the weak intercalation, and rock collapse from the slope crest. However, the dynamic failure mode of the counter-bedding slope is mainly represented by staggered horizontal and vertical fissures, extrusion of the weak intercalation, and breakage at the slope crest.

“…HUANG et al [14] performed a series of tilting table tests to study the factors that may influence the failure mechanism of reinforced slopes. Centrifugal tests [15], full-scale model tests [16], and shaking table tests [17] are other common types of experimental researches to investigate the behavior of reinforced soils.…”

The required reinforcement force to prevent instability and the yield acceleration of reinforced slopes are computed under seismic loading by applying the kinematic approach of limit analysis in conjunction with the pseudo-dynamic method for a wide range of soil cohesion, friction angle, dilation angle and horizontal and vertical seismic coefficients. Each parameter threatening the stability of the slope enhances the magnitude of the required reinforcement force and vice versa. Moreover, the yield acceleration increases with the increase in soil shear strength parameters but decreases with the increase in the slope angle. The comparison of the present work with some of the available solutions in the literatures shows a reasonable agreement.

“…Experimental studies on the GRS walls with segmental wall facing panels have also been carried out (e.g., Bathurst et al, 2002;Matsuo et al, 1998;Ling et al, 2005). The eŠects of the facing inclination and shear resistance of the facing interface (i.e., strong connection of each segmental panel) on the seismic performance of GRS walls were highlighted through their experiments.…”

“…Because the concept of Newmark's method (NM method) is simple, there have been many studies to adopt the NM method for the evaluation of the earthquake-induced residual displacement of GRS walls (Matsuo et al, 1998;Cai and Barthurst, 1996;Huang and Wang, 2005). However, it should be noted that the sliding or rotating mass and its subsoil are assumed to be rigid in the NM method.…”

Based on a series of shaking table model tests, it was found that the eŠects of 1) subsoil and backˆll deformation, 2) failure plane formation in backˆll, and 3) pullout resistance mobilized by the reinforcements on the seismic behaviors of the geosynthetic reinforced soil retaining walls (GRS walls) were signiˆcant. These eŠects cannot be taken into account in the conventional pseudo-static based limit equilibrium analyses or Newmark's rigid sliding block analogy, which are usually adopted as the seismic design procedure. Therefore, this study attempts to develop a simpliˆed procedure to evaluate earthquake-induced residual displacement of GRS walls by re‰ecting the knowledge on the seismic behaviors of GRS walls obtained from the shaking table model tests.In the proposed method, 1) the deformation characteristics of subsoil and backˆll are modeled based on the model test results and 2) the eŠect of failure plane formation is considered by using residual soil strength after the failure plane formation while the peak soil strength is used before the failure plane formation, and 3) the eŠect of the pullout resistance mobilized by the reinforcement is also introduced by evaluating the pullout resistance based on the results from the pullout tests of the reinforcements. By using the proposed method, simulations were performed on the shaking table model test results conducted under a wide variety of testing conditions and good agreements between the calculated and measured displacements were observed.
