Slope Tool (circular sliding)

Tips

• This tool is for slope stability analysis, as shown in the figure above.
• The slip surface is assumed as circular.
• The Swedish Method,the Fellenius Method, the Janbu's Method, and Bishop Method are adopted in this tool.
• Before calculation, please choose the applicable unit weight for different conditions.
• The Fellenius Method is only suitable for the condition using saturated unit weight.
• The unit weight of water is 9.8 (kN/m³).
• The start point of slip surface D should be located on AA1 or AB with only x_D as input.
• The lower slope angle β should be larger than the upper slope angle α.
• The factor of safety FS is defined as the ratio of resisting moment Mr to driving moment Md.
• If "nan", "0" or "inf" displays in Results, please check your input parameters.
