hello. can you help me with a matlab code to solve for the factor of safety of a slope using the morgentern-price method of slices?
I am a student and I am taking it as an assignment.
Slope stability analysis is carried out to safety in the design of a man-made or natural slopes (e.g. slopes, road cuts, surface mining, excavations, landfills etc.) And balance conditions. [1] [2] slope stability is the resistance of slippery slope to failure by sliding or collapse. [3] the main objectives of slope stability analysis are finding endangered areas, research on potential mechanisms fail, determining the slope sensitivity to different triggering mechanisms, designing an optimal slopes with respect to security, reliability and economy, designing possible corrective measures such as barriers and stabilization. [1] [2]
Successful design of the slope requires geological information and characteristics of the region, for example, properties of the soil/rock mass, slope geometry, groundwater conditions, variety of materials by faulting, joint or discontinuity systems, movements and tension in the joints, earthquakes etc. [4] [5] the presence of water has a detrimental effect on slope stability. Water pressure in the pores, fractures or other discontinuities in the materials from which the pit slope will reduce the strength of these materials. [6] choice of appropriate analysis technique depending on both local conditions and the possible mode of failure with careful consideration is given to the different strengths, weaknesses and constraints that are inherent to any methodology. [7]
Before the computer age stability analysis was carried out by a graphic or portable calculator. Today engineers have many opportunities to the analysis software to use, ranges from simple limit equilibrium techniques to computational limit analysis approaches (e.g. Finite element limit analysis Discontinuity layout optimization) to complex and advanced numerical solutions (finite-element-differentiated/codes). [1] the engineer must fully understand the limitations of each technique. Limit equilibrium so most used and simple solution method, but can be insufficient when the slope not by complex mechanisms (for example, internal distortion and brittle fracture, progressive creep, liquefaction of weaker soil layers, etc.). In these cases it would be more sophisticated numerical modelling are used. Also, even for very simple slopes, the results obtained with typical limit equilibrium methods currently in use (Bishop, Spencer, etc.) can vary significantly. Also, using the risk assessment and understanding. Risk assessment includes both the result of slope failure and the probability of failure (require both an understanding of the failure mechanism).

In the last decade (2003) slope stability Radar developed external scan a rock slope to the spatial distortion of the face. Small movements of a rough wall can be detected accurately with submillimeter interferometry techniques
