The article discusses the dynamic processes simulation in landslide slopes during dynamic effects. Dynamic effects can be caused by pulsed, including shock loads. Also, the movement of vehicles along the slope is considered. The solution is based on the general massive load movement dynamic problem formulation = on a massive basis. Discretization over the spatial domain is obtained in the finite element method (FEM) form. The equations solution is performed by the continuation method with respect to the time parameter. Direct methods of the integrating dynamics problems are used. Considering the high dimensionality of the problem in the spatial formulation, to construct a numerical solution, we use the previously obtained explicit absolutely stable direct integration schemes. The methods used can be considered as explicit, absolutely stable schemes for the direct integration of a dynamic problem with a variable mass in time. Recommendations for evaluating the numerical solution accuracy are given.
