Slope 2000 is a new era in slope stability analysis. It can locate the critical failure surface of a slope under general conditions with general constraints. The shape of the failure surface can be either circular or non-circular. It is probably the first program which can actually locate the critical non-circular failure surface of a slope under general conditions with user prescribed precision in the global minimum In fact, most of the existing programs can only locate the critical circular failure surface using a user defined grid as the centre of rotation (3 control variables). Some programs offer a search for critical non-circular failure surface using a random generation of non-circular failure surface. This approach requires large number of evaluations to achieve the accuracy as attained by Slope 2000. For pattern search of non-circular failure surface, 10 slices will require about 10^10 trials while only aound 20000 trials are required by Slope 2000. Slope 2000 is also probably the first program using the simulated annealing technique to locate the critical failure surface. The user can control the convergence criterion for the location of the critical failure surface which is another special feature not available in other similar programs. Slope 2000 is the ability to generate graphics file in several bitmap and vector formats. The Winodws version of Slope 2000 can also send the graphics to the clipboard for various purposes. Another exciting feature of Slope 2000 is the incorporation of circular 3D analysis using the Janbu simplified and rigorous method, Bishop method, Spencer method and Sarma using the approach by Hungr. Slope 2000 is able to accept complicated ground condition with multiple surcharge regions on or below ground surface. Soil reinforcement can also be defined and bond strength can be determined automatically. General capability
of Slope 2000 : 2. Any number of trapezoidal vertical and horizontal surcharge loads on or below ground surface. 3. Multiple perch water table and earthquake loads can also be used in the analysis. 4. Modelling of soil nails/geotextile can also be performed. The effective bond stress can be calculated automatically which greatly reduces the burden of the engineers. 5. No initial trial failure surface is required to de defined in the location of the critical failure surface. All these features are available for 2D as well as 3D analysis. For 2D analysis, the methods of analysis available are : Bishop, Janbu's simplified and rigorous, Spencer, Sarma, wedge method, Corps of Engineers, Lowe Karafiath, GLE and Morgenstern and Price methods (4 types of internal force functions.) For 3D analysis, the methods of analysis available are : Bishop, Janbu's simplified and rigorous method, Morgenstern and Price (4 interslice functions with Spencer as a special case), Sarma, Corps of Engineer and Lowe Karafiath methods. Platform : Slope 2000 is available
for Windows and DOS platform at present and Linux version may be produced
if necessary. Porting to other platform may be considered if necessary. |
