    The mechanical properties of these soils are weaker than the original in situ soils. However, the stiffness is calculated by the shear modulus of the in situ soil at the depth of the LRP point, and this shear modulus is larger than the shear modulus of trapped soft soils. As a result, the stiffness coefficient is bound to be reduced.
