Soil Layer [MPTE]

The Soil Layer definition is used to specify the characteristics of the soil. Various models are available in OpenBrIM.

Regarding soil models, note that when a soil model is selected, only the necessary parameters for that model are displayed to the engineer.

General:

Soil Type[Cohesionless/Cohesive/Rock]: Specify the soil type. Avaliable Soil Models are filtered according to the Soil Type.

Unit Weight: Specify the unit weight of the soil.

Top of Layer Elevation: This parameter specifies the global elevation of top layer of the soil.

Bottom of Layer Elevation: This parameter specifies the global elevation of bottom layer of the soil.

Lateral:

Model: Specify the appropriate model according to the definition of the soil material.

These are the currently avaliable lateral soil models in the OpenBrIM:

• Sand (Reese)

• Sand (API)

• Liquefied Sand (Rollins)

• Soft Clay (Matlock)

• Stiff Clay without Free Water (Welch and Reese)

• Stiff Clay with Free Water (Reese)

• Weak Rock

• Strong Rock (Turner)

• Limestone (McVay)

• Custom P-Y

For theoretical details about the models, refer to Lateral Soil Models.

Axial:

Model: Specify the appropriate model according to the definition of the soil material.

These are the currently avaliable axial soil models in the OpenBrIM:

• Driven Pile (McVay)

• Drilled Shaft Sand (Reese and O’Neill)

• Drilled Shaft Clay (Reese and O’Neill)

• Custom T-Z

For theoretical details about the models, refer to Axial TZ Soil Models.

Tip:

Model: Specify the appropriate model according to the definition of the soil material.

These are the currently avaliable tip soil models in the OpenBrIM:

• Driven Pile (McVay)

• Drilled Shaft Sand (Reese and O’Neill)

• Drilled Shaft Clay (Reese and O’Neill)

• Custom Q-Z

For theoretical details about the models, Axial QZ Soil Models.

Torsional:

Model: Specify the appropriate model according to the definition of the soil material.

These are the currently avaliable torsional soil models in the OpenBrIM:

• Hyperbolic Curve

• Custom T-θ

About Custom Models:

• The first point must be [0,0].

• All other points must have only positive values.

• At least three points must be entered.
