haoxiaomin. Experimental Study on the distance of rock falls under different influencing factors[J]. Advanced Engineering Sciences, 2016,48(6):1-7.DOI:
studied the distance of different shape and size rock falls under different peak acceleration seismic
sine wave frequency and slope shape
and cleared the influence of rock falls on the buildings at the slope foot.The results showed that: the distance of rockfall increased with the increasing of seismic peak acceleration
where the maximum distance was spherical rockfall
cylindrical
the square rockfall was inferior to the spherical rockfall
and the minimum distance was rectangle rockfall. With the slope angle increased
the distance of rockfall first increased and then decreased
and the maximum distance of rockfall appeared when the angle of the slope reached 50°. The distance of rackfall increased with the slope height increased. With increasing of sine wave frequency
the distance of rock falls decreased first and then increased. And the maximum distance from largest to smallest were spherical
cylindrical
square and rectangle rockfall. Based on the probability statistics method
the maximum distance of rockfall distributed within the 1.6H
which provide reference for protection design of the structures at slope foot.
