Problem: Find the slope of the line joining the points representing i and -(square root of 2)+i on the complex plane. Mathematical modelling of slopes UPC, Barcelona, Spain bInternational Center for Numerical Methods in Engineering Abstract The paper discusses first the effect of rainfall on the stability of slopes and it focusses on the role of permeability. Existing or induced discontinuities are shown to have a remarkable effect on the slope safety.

Limit equilibrium concepts alone cannot answer these questions. This paper will discuss and provide examples of the slope analysis tools that are available to the engineer, emphasising recent developments in numerical methods in the analysis of complex rock slope deformations. Kinematic and limit equilibrium analysis of rock slopes Cited by: The last decade has seen considerable advances in the application of numerical modeling to rock slopes.

In this chapter we present the current state of the art, beginning with simple kinematic and limit equilibrium approaches and then moving on to continuum and discontinuum modeling by: 9.

( Numerical methods with a discontinuum model such as the DEM can estimate the large deformation and discontinuous collapse behavior, which make it preferable over methods such as the FEM to examine large slope deformations.

However, selection of discontinuum model parameters for input, such as spring and dashpot constants, is a crucial by: 8. Stead D, Coggan JC () Numerical modelling of rock slopes using a total slope failure approach.

This method can give information about the deformations at. In addition, FEM/DEM-DFN modelling is applied to the preliminary analysis of the block caving triggered slope failure at Palabora open pit.

This research represents a valuable contribution to block caving geomechanics and is a major step forward in the understanding of complex block caving subsidence phenomena, paving the way to more reliable. illustrates the use of the 2-D limit equilibrium program SLOPE/W in the back -analysis of a failure in a kaolinised granite slope.

Slope stability analyses include static and dynamic, analytical or empirical methods to evaluate the stability of earth and rock-fill dams, embankments.Modelling forms an implicit part of all engineering design but many geotechnical engineers are insufficiently aware of the assumptions they make, or the nature and consequences of those assumptions.

This book will enable practicing engineers to make informed decisions concerning soil model, boundary conditions, and the choice of elements in.
