- This tool is for retaining wall analysis, as shown in the figure above.
- This tool is suitable for cantilever and gravity retaining walls using Rankine earth pressure theory.
- Two homogenous soil layers are considered in the analysis.
- The backfill layer is granular soil, and the cohesion c
_{1}is assumed to be zero. - The normal requirements for the stability check are listed as: FS
_{O}(Safety factor of overturning) > 2; FS_{S}(Safety factor of base sliding) > 1.5; FS_{B}(Safety factor of bearing capacity) > 3. - All the input parameters should be positive.
- For "nan", "0" or "inf" displayed in Results, please check your input parameters.
