    Dec 01, 1986 The seismic stability of an embankment resting on saturated sand layers was studied by carrying out shaking table tests using large models. This paper is concerned with the failure mode of embankments during earthquakes; the slope stability analysis method used here is based on the assumption of failure along a circular arc (Circular Arc Analysis)

    Dec 03, 2021 Abstract. The large-scale shaking table model test, which can directly reproduce the process of slope instability and failure, is an important technical means for the prediction and evaluation of slope seismic stability. However, up to now, the systematic slope stability evaluation method based on the shaking table slope model test has not been established
