The seismic stability of an embankment resting on saturated sand layers was studied by carrying out shaking table tests using large models.This paper.
Seismic evaluation of embankment by shaking table test and finite element method.Abdoullah namdar and azam khodashenas pelko mysore university, mysore, india.Email abnamdaryahoo.Com abstract the shaking table test and finite element method were used for simulation embankment model.In the shaking table test through the acceleration.
Simulation of shaking table test for eps embankment model by distinct element method.In designing structures in japan, where a lot of earthquakes occur, it is indispensable to check their stability during earthquakes.This is especially true in the case of structures using eps, which are apt to be topheavy.
However, shaking table testing on the liquefaction of soil is limited in south korea.For this purpose, an investigative study on the liquefaction of a geotextiletube reinforced embankment laid on saemangeum dredged soil, which is classified as silty sand sm and is most liquefiable, was conducted by means of a shaking table test.In addition,.
Shaking table study of slopes.Seed and clough 1963 also used shaking table tests to study the earthquake resistance of sloping core dams.Wartman et al.2003, 2001 conducted a small scale shaking table test to simulate slope behavior under a 1g gravity field.Lin and wang 2006 used a largescale shaking table test model on sandy slope.
Abstract the shaking table model test was conducted to investigate earthquake resistant behavior of stone columns under the intensity of an earthquake resistance of buildings is viii.The test results show that when acceleration is less than 0.20 g.

The shaking table model test was conducted to investigate earthquake resistant behavior of stone columns under the intensity of an earthquake resistance of buildings is viii.The test results show that when acceleration is less than 0.20 g, composite foundation is not liquefied, settlement is also small and pile dislocation is not observed.
Shaking table tests model design and material properties for the lower part being reinforced and retained, the road embankment investigated can be simplified and generalized as a symmetrical model for shaking table tests.As shown in figure 6a, the layered shear deformation model box was used as the test model box,.
For each test a large model of an embankment on a saturated sand layer was placed in a shaking table box 8 m in length, 4 m in width and 2 m in height.The failure of the embankment was investigated by measuring the rapid rapid increase in residual settlement and lateral displacement in accordance with the increase in table acceleration.
Purpose of the shaking table test was to investigate this concern.The shaking table test was performed on a 1 to 65 scale model.The soft organic soil was modelled by a gelatin based solution while the embankment was modelled by a compact sand.The piles were modelled by lengths of 6.4 mm dia.

Beneath the embankment.Shaking table test configuration of model embankment and pbd installation the model test was carried out by constructing a reduced size embankment of 100mm height on a 400mm thick foundation soil in a simple shear box having a size of 700mm width x 1500 mm breadth x 700 mm height as shown in fig.2.
Shaking table test results and analytical calculation results are given in table 3.The shaking table dynamic force quickly collapsed the system it was difficult to clearly observe slope failure shape.The pore pressure sensors helped to recognise nonlinear liquefaction.Table 1.Characteristics of shaking table embankment model.
