Lateral displacements parameters
•Level ground (no calculation will be performed): When checked CLiq will not perform any calculation for the estimation of lateral displacements.
•Gently slope ground: This is the default selection. Lateral displacements will be performed based on the slope value entered (value must be larger than 0.20% and smaller than 3.50%). If liquefaction is calculated at large depth the resulting lateral displacement can be excessively high (since the program sums up all shear strains regardless of depth). The user has the option to apply a linear weighting factor to the shear strains (gamma) to avoid excessive lateral displacements. The linear weighting is similar to the weighting applied to vol. strains (ev) and extends to a depth of 18m.
•Level ground with free face: When checked the software will estimate lateral displacements based on the geometry profile specified. L field holds the horizontal distance of the CPT from the slope toe, and H field holds the vertical height of the slope. When the Ignore displacements below 2H check box is checked, calculation of the estimated lateral displacements will not be performed for points that lay below a depth of 2xH from the ground surface (minus the fill height if specified).
