REAME for Cylindrical Failure
Slopes of any configuration with a large number of different soil layers can be handled.
Seepage can be considered by specifying a piezometric surface or a pore pressure ratio. If necessary, several different seepage cases can be considered simultaneously to save the computer time.
Either the static or the seismic factors of safety can be computed.
Either the simplified Bishop method or the normal method can be used to determine the factor of safety. When the normal method is specified and the most critical circle is found, the factor of safety for this particular circle based on the simplified Bishop method is also printed.
More flexibility is allowed in radius control. One or more radius control zones can be set up, and the number of circles in each zone specified.
The factors of safety at a number of individual centers or at a group of centers, which form a grid, can be determined. By selecting one or more trial centers, a search routine can be activated to locate the minimum factor of safety. To obtain the minimum factor of safety in one run, the automatic search can follow immediately after the grid, using the most critical center obtained from the grid as the initial trial center for the search.
To preclude the formation of shallow circles, a minimum depth may be specified. Any circle having the tallest slice smaller than the minimum depth will not be run.
A cross section of the slope can be plotted by the printer, including all soil layers, the piezometric surface, and the most critical circle.
