Slope stability analisys on AutoCAD

AEC Slope is a CAD based design software for checking and reporting safety factors on a proposed bank section drawn on AutoCAD platform. 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 results 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 is used for analyzing stability of slopes for the above structures and reporting safety factors. The most important cause of failure is by sliding. It may occur slowly or suddenly and with or without fore-warning. Such a failure causes a portion of the earth fill to slide downwards and outwards with respect to the remaining part generally along a well-defined slide surface. It is, therefore, necessary that the designer takes special care to eliminate any possibility of such a failure. These results can be cross verified /proof checked from the AutoCAD drawing for any number of sample checks or in a batch check when the data is exported to Excel file and formulas are fed to relevant excel cells. AEC Slope automatically reads the Drawing objects drawn in 2D poly lines. AEC Slope works on Draw Down and Steady Seepage on Up-Stream and Down-Stream respectively with and without earthquake. AEC Slope automatically identifies Zones above or below phreatic line or submerged to compute driving and resisting forces. In determining the stability of the proposed slope it is necessary to try many different circles as one trial arc gives the value of factor of safety for that arc only. The circle which yields the minimum value of factor of safety is the most critical. Theoretically it is necessary to try an infinite number of possible failure circles with different centres and radii before the most critical one giving lowest accepted factor of safety may be located. After trying numerous failure circles under various combinations of radii and locus settings if the lowest value of factor of safety is acceptable the profile of the section needs no changes and the assumed profile shall be considered adequate from considerations of stability.
