High Rock Slope

The meshless methods are particularly suitable for modeling problems with discontinuities such as joints in rock mass. The meshless Shepard and least squares (MSLS) method is a newly developed meshless method, which overcomes some limitations with other meshless methods. In the present paper, the MSLS method is extended for modeling jointed rock mass and the joint is modeled as discontinuity governing the near-field stress. A substantial high rock slope by the dam shoulder of Jinping Hydropower Station is analyzed by the developed method. Safety factors are evaluated based on the stress results along potential slip surfaces and compared with the conventional slice methods. The results demonstrate the feasibility of using the MSLS method in rock slope stability analysis and also reveal some interesting differences from the conventional slice methods. Some findings and outstanding issues demonstrated in this study are discussed in the end, which can be the topics for future development.

Considering the features of slope rock mass failure, this paper applies residual thrust method and linear programming theory on the basis of finite element method, to assess safety of each cell of slope rock mass in dangerous zone. According to the slip field method to determine three-dimensional slope slip surface, to deduce three-dimensional stability analysis method based on symmetry breaking, a C++ based 3D-slope program is developed for purposes of three-dimensional slope stability analysis. Finally get the most dangerous landslide geometry and its safety factor, In the paper, combining with the engineering examples, the calculating results are comfortable to the practical failure.

Introduction. In the course of mining mineral deposits by opencast, natural stress state of adjacent rock mass changes giving rise to geomechanical processes which lead to pit slopes deformation. It can be prevented by mean of detecting landslide-hazardous zone by using three-dimensional geological-geophysical models based on the data bases from prospecting surveys and geophysical sounding of the adjacent rock. Research aim is to develop and evaluate basic provisions of the methods of forecasting slope stability based on three-dimensional geological-geophysical models which include the following information: the results of geophysical sounding (waterlogged zones boundaries); databases of exploration wells (physicalmechanical properties of soils in the zones of water saturation and natural moisture content, and the relief of the natural surfaces of weakness); design and actual position of mine workings. Methodology. In order to find the most hazardous section in the adjacent rock mass an algorithm of forecasting has been proposed and adjacent rock mass stability has been analyzed based on threedimensional geological-geophysical models. Results. A three-dimensional geological-geophysical model of Centralny landslide has been constructed as a result of analyzing geological survey databases, surveying instrumental observations over the deformations, and electrical sounding of the adjacent rock mass. Values of the friction angle and cohesion were found with using the inverse calculation method. Centralny landslide stability forecast has been analyzed as of the year of 2018 and after the final completion of the first stage of loading-out the front section in 2025. Summary. Developed an algorithm of slope stability analysis makes it possible to solve the task of finding the most hazardous section or landslide area by means of computer-based realization.
