Other AbstractUndercutting-erosion exists commonly in the breaking process of landslide dams.Due to the limitations of the formation mechanism and the gully terrain,however,many dams have a height difference in the transverse direction,which causes that the lateral erosion in the dam-breaking is unidirectional.The evolutional characteristics of landslide dams under the combination of unidirectional lateral-erosion and undercutting-erosion were studied by experiment test and numerical simulation.The test results show that,for the situation where the dam material completely comes from the gully,the failure scale of the breach slope resulted from the combination of unidirectional lateral-erosion and undercutting-erosion gradually increases.For a huge dam with a large height difference in the transverse direction and under the combination of unidirectional lateral-erosion and undercuttingerosion,a secondary landslide would occur with increasing the height of the breach slope.The formation of the secondary landslide was demonstrated by numerical simulation.Based on the theory of soil mechanics,an arc sliding model was proposed to predict the radius and failure area of the secondary landslide.The model has a certain practicality as the calculated value differs from the theoretical value by only 6.2%.
