Cohesive soils types
WebType A – Cohesive soils with an unconfined compressive strength of 1.5 tons per square foot (tsf) (144 kPa) or greater. Examples include: clay, silty clay, sandy clay, and clay loam. Certain conditions preclude soil from being classified as Type A. For example, no soil is Type A if it is fissured or has been WebThe soil be- haviour type index (Ic) is computed after normalising the cone tip resistance (qc) and the shaft friction (fs) with effective stress (Qt, Fr ) (Equation 7 and 8). It can be used to give a first indication of the soil type based on an interpretation of the Robertson classification chart [26].
