Pset_SolidStratumCapacity Properties expressing the capacity of a stratum using physical measures. Regional and National conventions should be captured through classification and specific property sets. IfcGeotechnicalStratum/SOLID IfcGeotechnicalStratum/SOLID CohesionBehaviour Cohesive shear strength of a rock or soil that is independent of interparticle friction. FrictionAngle Friction angle is the tested inclination angle from horizontal. FrictionBehaviour Friction shear strength of a rock or soil that is dependent on interparticle friction. GrainSize Grain size diameter. HydraulicConductivity Hydraulic Conductivity (permeability) of soil for water, given with the K or Kf value in m/s LoadBearingCapacity Estimate or design maximum load bearing capacity of the defined surface/structure (e.g. soil stratum or planar slab). Represented as a force per unit area measurement. NValue Blow count from standard penetration testing, to ISO 22476-3, ASTM D1586[1] and Australian Standards AS 1289.6.3.1, which correlates to other engineering properties of soils. PermeabilityBehaviour Proportionality constant in Darcy's law which relates flow rate and viscosity to a pressure gradient applied to the porous media. PoisonsRatio Ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force. PwaveVelocity P-wave velocity of a rock or soil. Resistivity Electrical resistivity (Ohm-m). SettlementBehaviour Estimate of the settlement/compaction behaviour of the stratum. SwaveVelocity S-wave velocity of a rock or soil.
