  • seismic response of geocell retainingwalls through

    Mar 05, 2016 · Leshchinsky et al. and Ling et al. presented the results of shaking table tests on five large-scale models of geocell retaining walls, each 2.8 m high, constructed with different geocell and geogrid combinations and subjected seismic shaking corresponding to Kobe earthquake of 1995. All these model walls performed satisfactorily under the simulated earthquake motions

  • seismic response of a newly developedgeocell-reinforced

    In this paper, to check whether geocell-RS RW backfilled with poorly graded gravels has a substantially high seismic stability, two shaking table model tests on geocell-RS RW and geogrid-RS RW backfilled in poorly graded gravels were carried out. A conventional-type RW …

    Jan 01, 2020 · Fig. 1 displays the test layout and dimensions of the shaking table and its instrumentation. The shaking table had two 36 mm-thick 200 × 60 cm wood blocks, where upper wood block served as a dock on which a container was placed and the lower wood block served as a fixed support; three 1.2 mm-thick steel plates which each of them were enclosed by four 50 × 50 × 5 mm …

  • effect of facingslope on the seismic response of geocell

    Latha and Manju (2018) carried out shake table tests to know the effect of the slope of the geocell wall on its seismic performance. The geocells were prepared with High-Density Polyethylene (HDPE

  • equivalent seismic coefficient in geocell retention

    Feb 01, 2009 · Reported here are relevant results of shake table tests on five different geocell structures, each 2.8 m high, subjected to an excitation simulating the Kobe earthquake. Exhumation enabled the tracing of slip surfaces that developed during the shaking. Back-analysis resulted in the fraction of the applied PGA needed to establish a slip surface

  • shaking tabletestson reinforced soil retaining walls

    Mar 20, 2020 · In this paper, shaking table tests were carried out in model-scale to investigate seismic performance of RSRW subjected to the combined forces of rainfall and earthquakes. Five cases with different degrees of saturation for the model ground were considered for comparison and each wall was shaken by a horizontal motion with a peak acceleration of 0.5 g

  • deformation and localisation behaviours of reinforced

    Feb 01, 2020 · Despite the advantages of testing models with 1g shaking table, the results may somehow be different from the behaviour of the conceived prototype structures (Munoz et al., 2012, Tatsuoka et al., 2012) due to (i) pressure level and (ii) particle size effects, i.e. effects of the ratio of particle size to model size.Nonetheless, GRS RW model tests are likely to be suitable for stability

  • seismic responseof geocell retaining walls: experimental

    Ling et al. (2009) conducted a series of shaking table tests of a geocell-facing retaining wall, finding that geocells show higher seismic stability compared to the conventional geogrid-reinforced

    The main objective of this research was to model the zonation of wrap faced embankment on soft clay foundation, by applying a shake table test. Also, to investigate the dynamic behaviors of clay

  • shaking table tests on gravel slopes reinforcedby

    Aug 01, 2020 · To accurately simulate the dynamic response of a reinforced slope, appropriate similitude rules are required for the test. In this study, the similitude laws presented by Iai (1989) were used; these laws are widely adopted, being employed in many 1-g model tests. In accordance with the bearing capacity of the shaking table, the similarity ratio to the geometric size was determined to be 1:6

    Jan 15, 2020 · Numerical simulation and shaking table test results for the CS8 are shown in Fig. 24. For the CS4, the maximum errors between numerical simulation results and shaking table results are 5.3% and 10.0% in X and Y directions, respectively. For the CS8, the maximum errors are 12.0% and 4.5% in X and Y directions
