Effect of topography on the motion parameters and deposition characteristics of deflection-type rock avalanches using the discrete element method

Abstract In this study, the deflection-type rock avalanches, a typical moving form of landslide in mountainous regions, were selected as the research object. Basing on the analysis of topography features of this type of rock avalanche, the discrete element method (DEM) was used to simulate the mass...

520			\|a Abstract In this study, the deflection-type rock avalanches, a typical moving form of landslide in mountainous regions, were selected as the research object. Basing on the analysis of topography features of this type of rock avalanche, the discrete element method (DEM) was used to simulate the mass movement process of rock avalanche under different combinations of topographic factors for analyzing the effect of topography on rock avalanche. Sensitivity analysis for topography shows that the travel distance and the velocity difference are confined by the restraint of slope-toe and deflection effects. The slope inclination of deposition area and flow area are the most significant factors for the travel distance and velocity difference, respectively. In addition, a multivariate regression model was proposed to describe the relationship between motion parameters and main topographic factors. Regarding to the velocity distribution of granular particles inside granular body, the relationship between velocities of granular particles and deposit thickness follows a power law distribution under the different deposit width and length, but there are significant differences in power exponents. As for the granular particle distribution inside a deposit body, there is an obvious inverse-grading structure of granular particles inside the deposit body due to the separation of granular particles in their movement.

Basing on the analysis of topography features of this type of rock avalanche, the discrete element method (DEM) was used to simulate the mass movement process of rock avalanche under different combinations of topographic factors for analyzing the effect of topography on rock avalanche. Sensitivity analysis for topography shows that the travel distance and the velocity difference are confined by the restraint of slope-toe and deflection effects.

abstract	Abstract In this study, the deflection-type rock avalanches, a typical moving form of landslide in mountainous regions, were selected as the research object. Basing on the analysis of topography features of this type of rock avalanche, the discrete element method (DEM) was used to simulate the mass movement process of rock avalanche under different combinations of topographic factors for analyzing the effect of topography on rock avalanche. Sensitivity analysis for topography shows that the travel distance and the velocity difference are confined by the restraint of slope-toe and deflection effects. The slope inclination of deposition area and flow area are the most significant factors for the travel distance and velocity difference, respectively. In addition, a multivariate regression model was proposed to describe the relationship between motion parameters and main topographic factors. Regarding to the velocity distribution of granular particles inside granular body, the relationship between velocities of granular particles and deposit thickness follows a power law distribution under the different deposit width and length, but there are significant differences in power exponents. As for the granular particle distribution inside a deposit body, there is an obvious inverse-grading structure of granular particles inside the deposit body due to the separation of granular particles in their movement.

Basing on the analysis of topography features of this type of rock avalanche, the discrete element method (DEM) was used to simulate the mass movement process of rock avalanche under different combinations of topographic factors for analyzing the effect of topography on rock avalanche. Sensitivity analysis for topography shows that the travel distance and the velocity difference are confined by the restraint of slope-toe and deflection effects. The slope inclination of deposition area and flow area are the most significant factors for the travel distance and velocity difference, respectively. In addition, a multivariate regression model was proposed to describe the relationship between motion parameters and main topographic factors. Regarding to the velocity distribution of granular particles inside granular body, the relationship between velocities of granular particles and deposit thickness follows a power law distribution under the different deposit width and length, but there are significant differences in power exponents. As for the granular particle distribution inside a deposit body, there is an obvious inverse-grading structure of granular particles inside the deposit body due to the separation of granular particles in their movement.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Deflection-type</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Rock avalanches</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Topographic factors</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sensitivity analysis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Motion parameters</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Particle distribution</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xiangjun, Pei</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xiaoyi, Fan</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Arabian journal of geosciences</subfield><subfield code="d">Berlin : Springer, 2008</subfield><subfield code="g">13(2020), 18 vom: 07.
