Influence of Internal Structure on Breaking Process of Short-Lived Landslide Dams

The diversity of the landslide dam structure will result in difference body’s seepage. In this paper, based on two kinds soil bodies different particle gradations, fourteen groups structures are designed to generalize seepage developments and breaking processes. study shows that saturation evolution characteristics dam's have a considerable influence dam’s characteristics. An empirical formula is fitted according time-seepage degree curve dams processes predict forms before break. During water storage process dam, seepage's inside body reduces stability thus affecting failure after it has started. experiment, found growth rate inversely proportional breach area. Although internal penetration usually undervalued, verifies conductive for further understanding mechanism dam.
