This paper describes how overconsolidation affects the shear modulus at small strain (G0) for peat, as well as the strain dependence of the shear modulus (G) and the damping ratio (h) of overconsolidated peat. Hayashi et al. (Soils Found 52(2):299–

In cold regions, the road surface sometimes deforms from frost heaving of the subgrade. For this reason, road construction in the cold regions of Japan is done by using non-frost heaving materials for the layers within the frost penetration depth of

When the soil generated during road or river excavation work is too soft to be used as a material, it can be improved by the use of solidifiers such as cement and lime. However, if an embankment has excessive strength as a result of solidification, t
