| LoadingType |
Loading type |
- |
- Staged construction
- Consolidation and simultaneous loading in the sense of changing the load combination, stress state, weight, strength or stiffness of the elements, activated by changing the load and geometry configuration or pore pressure distribution by means of staged construction.
- Minimum excess pore pressure
- Consolidation without additional loading, until all excess pore pressures have decreased below a certain minimum value, specified by the minimum pore pressure parameter.
- Degree of consolidation
- Consolidation without additional loading, until a desired degree of consolidation, specified by the degree of consolidation parameter, is reached.
- Target SumMsf
- Reduction of the soil and interface strength towards a target value of the total multiplier ΣMsf. The program first performs a full safety analysis until failure and then it recalculates the last step before the target value of ΣMsf in order to reach the target exactly.
- Incremental Multiplies
- Reduction of the soil interface strength parameters by using Incremental Multipliers option.
