Study on Seismic Stability of Sandy Slope in Different Underground Water Levels
Based on the finite element model and shaking table test
the laws of seismic dynamic response and failure mode influenced by underground water are studied.The test results show the safety factors calculated by the Chinese specification are conservative compared with the Japanese specification based on the pseudo-static method.With the increase of groundwater
the maximum horizontal displacement of slope shows increasing trend
and reaches maximum horizontal displacement on the top of the slope
and the displacement under near-field earthquake is greater than that under far-field earthquake.The maximum accelerations at the top of slope show decreasing tend with the increase of groundwater
which shows that the existence of groundwater damps vibration.Without considering the groundwater
the destruction of slope is mainly the circular shearing damage through the slope toe
while the destruction is not yet through the slope toe
but from a point on the front of slope.Finally
based on the comparison of shaking table test and the numerical simulation
the accuracy of numerical simulation results of this paper are verified.
