EnSlope is a simple, easy to use, 2D, slope-stability program based on the limit-equilibrium method. Engineers can create and run a slope-stability model in less than 10 minutes after following a few short tutorial videos. The speed buttons in the program are intuitive and make using EnSlope as easy as a few clicks of the quick-access buttons!
The new EnSlope software is based on enhancements of the methods for slope stability analyses established by the STABL series of programs, initially developed by Ronald A. Siegel at Purdue University in 1975. The original STABL has been available since 1976, with an open release from the Indiana Department of Highways. After its release in the open literature, the program was later adopted by many other agencies. Currently, the STABL programs are well accepted tools for analyzing the stability of slopes by various state highway agencies in the United States.
The original STABL programs were developed for mainframe computers and adapted to personal computers using a command-line format for data entry. The new EnSlope uses enhanced-graphics interface to implement pull-down menus, dialog boxes, option buttons, and grid-cells for data entry. The user may read information on the screen, then type input at the specified entry field. The entered data can be easily changed by moving the mouse to the location of a particular field. The graphics module allows the user to view failure surfaces, boundary lines, water surfaces, surcharge loads, and other features.
In addition, EnSlope allows the user to analyze a reinforced-earth slope as well as a slope stabilized by piles or drilled shafts. It also allows for the use of either English units (ft and lbs) or S.I. units (meter and kN). The program helps with unit conversions if the user selects to change from one system of units to the other.
