AEC Slope 2009 - Slope Stability Analyzer
Earth embankments are widely used for roads, railways, river training works, canal
embankments, dams, etc. The main economy and safety of these works can be accomplished
by adopting proper and economical methods of design. Failure of these structures
is likely to result in loss of life and damages to property. It may also result
in damage and/or washout of the structure fully or partially. AEC Slope 2009 is
used for analyzing stability of slopes for the above structures and reporting safety
factors.
Components Of Earth Dam

Impervious blanket
Method of Stability Analysis
There are many methods of analysis for determining the stability of slopes.
The method of slices, called the Swedish method of analysis.
In this method, a surface of failure of embankment is assumed and the factor of
safety of
embankment worked out.
This process is repeated with a number of trial surfaces and the one with the least
factor of
safety is called the critical slip surface.
If the factor of safety for the critical slip surface is more than one, the slope
is taken to be
stable.
The Swedish method assumes that the slip surface is an arc of a circle.
AEC Slope 2009 –Analysis
AEC Slope 2009 considers total stress method of analysis on AutoCAD platform.
It does not consider pore water measurements.
No shearing stresses act across the plane of the cross section and the analysis
is treated as
two dimensional of embankment worked out.
The section of the dam analyzed is of unit thickness of safety is called the critical
slip surface.
The sliding mass is divided into a convenient number of slices.
Each slice is assumed to act independently of its adjoining slices.
The forces acting on the sides of a slice have no influence on the shear resistance.
The shear strength of the various zones along the potential failure surface is mobilized
simultaneously.
