Gharakhanlou M. Impact of anthropogenic factors on the surface and underground land sliding activity

Suggested an integrated model of water erosion for numerical simulation, which includes three interrelated components: a non-linear deformation of the soil environment, planar ground ablation and nonsteady filtration. This allows significantly extend the range of applications of mathematical modeling in geotechnical problems. Developed problem-oriented finite elements for a comprehensive stability analysis of the territories under the influence of technogenic factors. Based on this, the designed ratio of finite element method for an integrated stability model of landslide-prone areas was built for the first time. There was developed a method of laboratory testing for planar soil ablasion. As a part of a multifactorial experiment principles of selected highly significant factors in the planar slope soil ablasion were established. There were developed algorithms of successive transitions from one task to another by setting initial and boundary conditions, estimating changes and corresponding correction of ground bases’ bedding boundaries and computing an additional system of hydrodynamic forces. There was also executed program implementation and testing on examples. There were obtained new solutions of applied problems, analyzed stress-strain state of the slope, hydrogeological conditions, given estimation of the hydrodynamic forces’ contribution to the general system of forces acting on a slope, predicted behavior of the "foundation-slope-construction" system at the example of several experimental sites. All the above listed in complex allowed providing a series of effective activities on the engineering protection of territories
