Experimental study on raindrop splasherosion of Fujian earth building rammedearth material

摘要

By using different diameter raindrops on the earth building rammed earth wall of Yongding to testthe splash erosion, study of different rain diameters, slope, composed of different soil effects onrammed earth walls of raindrop splash erosion, further analysis of single raindrop splash onrammed earth material corrosion mechanism concluded the curve and the regression equationbetween natural rainfall intensity and rammed earth material of splash depth. Results show thatthe splash erosion amount is related to rain diameter, slope and wind speed, the composition ofthe soil is the significant factor influencing splash erosion, different rammed earth splash depthsand natural rainfall intensity form into different functional relation.
