Shallow Foundation Tool (S_c)

Tips

• This tool is for calculating consolidation settlement of the caly layer below the center point of the shallow foundation, as shown in the figure above.
• The theory of one-dimensional consolidation settlement is adopted in the calculation.
• Only the primary consolidation settlement is considered in the calculation.
• σ′_c is preconsolidation pressure. If the "normally consolidated state" is given for clay with unkown of σ′_c, users can just input "0". For overconsolidated clay and from overconsolidated to normally consolidated clay, users should input corresponding real value.
• σ′_z0 is the stress in soil at the middle of the clay layer.
• Before calculation, please choose a method used for obtaining averaged vertical stress increment of the clay layer.
• All the input parameters should be positive.
• The unit weight of water is 9.8 kN/m³.
• For "nan", "0" or "inf" displayed in Results, please check your input parameters.
