Abstract

To understand the mechanisms of slope failure during earthquakes, shaking table tests were conducted using a large-scale slope model, and the seismic response acceleration of the displacement of the slope was measured. Using the data of the slopes that collapsed during the Hyogo-ken Nanbu Earthquake, a slope model was prepared, which measured approximately 4 m long and 3 m high, and was inclined at 45 degrees and had a soil layer 1.2 m thick. Forces that imitated seismic waves were repeatedly applied until the slope fell by changing the seismic acceleration. The test showed 1) sudden increases in response acceleration at the upper part of the slope, especially along the knick line where the head of the fallen soil mass was formed, 2) accumulation of displacement even in deep ground sections during the initial stages of failure, and 3) sudden formation of the sliding surface in the shallow section of the slope, which caused the overlying soil mass to slide.
