InitialPhase - PLAXIS 3D Input objects documentation


Initial phase object.
Property Long name Unit Description
Name Name - Name of the initial phase.
Comments Comments - Comments on the initial phase.
UserFeatures UserFeatures - UserFeatures of the initial phase.
Number Number - Number of the initial phase.
Identification Identification - Identifier of the initial phase.
PreviousPhase Previous phase - The phase that will take place before this phase.
ShouldCalculate Should calculate -
The initial phase will be calculated.
The initial phase will not be calculated.
DeformCalcType Deformation calculation type -
K0 procedure
This calculation type can be used to define the initial stresses for the model, taking into account the loading history of the soil.
Gravity loading
The phase will be calculated using a plastic calculation, in which initial stresses are generated based on the volumetric weight of the soil.
Flow only
The phase will be calculated using no effective stresses.
Field stress
This calculation type can be used to define a homogeneous initial stress state in the model, taking into account a rotation of principal stresses. This might be relevant for applications in deep soil or rock layers where the formation of these layers in the geological history has caused a rotation of principal stresses (shearing).
TimeInterval Time interval Time Total time period considered in the initial phase.
PorePresCalcType Pore pressure calculation type -
Direct generation of steady-state pore pressures from phreatic level and cluster-related conditions.
Steady state groundwater flow
Flow calculation to determine steady-state pore pressures and phreatic level based on hydraulic conditions. Input of soil permeability is required.
