- This tool is for analysis of retaining walls with geotextile reinforcement, as shown in the figure above.
- Two homogenous soil layers are considered in the analysis.
- The Rankine earth pressure theory is used.
- No surcharge is considered in this case.
- For the backfill, the cohesion c
_{1}is assumed to be zero. - The height of retaining wall H is suggested to be an integral multiple of S
_{V}vertical spacing of layers. - The friction angle at geotextile-soil interface is assumed as 2/3φ′
_{1}. - All the input parameters should be positive.
- For "nan", "0" or "inf" displayed in Results, please check your input parameters.
