Other Abstract

Based on the laboratory small-scale shaking table test,the dynamic response laws,deformation and failure characteristics of gravelly soil slopes at different groundwater levels were studied,which can be used as references for the seismic design of slopes. Tests revealed that the groundwater contained in slope served vibration absorption. The horizontal and vertical accelerations of the middle and lower parts of the slope with groundwater showed a tendency of decreasing with height downward,whereas in the upper part of the slope it presented an upward trend. Under the condition of the same vibration intensity,with the ascent of groundwater level,the weak zone of dynamic response increased and the shock absorption capacity increased. The higher the groundwater level,the smaller the acceleration amplification coefficient was found at the top of the slope. No groundwater slope occurred deformation and failure mainly in the top of the slope; Deformation in the groundwater slope took place and come to failure mainly in the slope foot. The increase of groundwater level and vibration strength aggravated the degree of foot damage.
