The system analysis of landslide-prone slopes stress state in terms of seismic and anthropogenic hazards and destabilizing risk factors
There is developed a methodical-algorithmic toolkit for the system modeling of the landslide-prone slopes stress state, implementing the new concept and strategy in solving the inverse problem of a sustainable location for the buildings and the constructions in the landslide sites in conditions of destabilizing soil masses degradation factors. There are involved the suggested principles of guaranteed term to prevent shifting slope, timely detection and elimination of the possible landslide-prone slopes activation causes on base of the systematically agreed tolerance freelance ground failures mode risk resources evaluation. There is carried out the calculation of piles-anchors in the holding landslide protection constructions with the phased implementation of the constructions’ work inspection in landslide thicker to "climb" and "punching", the assessment of soil stability and the definition of internal efforts to check the strength of the spile cross sections. The proposed computational scheme of interaction spile sealing and the surrounding soil is based on Fuss-Winkler elastic foundation model on considering experimentally obtained epures of the landslide pressure as a function of the length in the landslide thickness and its dive to a depth. The result of the calculation on "climb" through the construction and landslide masses "punching" is the length of the pile-spline in landslide column and limited pressure taking into account the length of the retaining members in the landslide thicker.
