An Introduction to Slope Stability Analysis

COURSE NO: G02-005
An Introduction to Slope Stability Analysis
Course Highlights

This online engineering PDH course presents the characteristics and critical aspects of the stability of excavation slopes; methods of designing slopes, including field observations and experience, slope stability charts, and detailed analyses; factors of safety; and methods of stabilizing slopes and slides. Slope stability analyses are useful in sands, silts, and normally consolidated and over-consolidated clays, but care must be taken to select the correct strength parameter.  The emphasis in this publication is on simple, routine procedures. It does not deal with specialized problems, such as the stability of excavated slopes during earthquakes.


Excavation slope instability may result from: 1) failure to control seepage forces in and at the toe of the slope, 2) too steep slopes for the shear strength of the material being excavated, and 3) insufficient shear strength of subgrade soils. Slope instability may occur suddenly, as the slope is being excavated, or after the slope has been standing for some time.


This 2 PDH online course is intended for civil engineers, structural engineers, geotechnical engineers, geologists and other design and construction professionals seeking an introduction to methods and techniques for addressing slope stability issues in earth structures and earthwork.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about slopes of cohesive and cohesionless soils on firm underlying strata
  • Learning about problems encountered with soft underlying strata
  • Learning about special problems encountered with stiff-fissured clays and shales
  • Understanding how to address issues encountered in loess soils
  • Knowing how to apply slope stability charts to address many common stability issues
  • Knowing how to apply the Method of Moments and the Method of Slices
  • Learning how to use the Simplified Wedge Method to address slope stability issues
