Function
- Set soil properties for the calculation of static earth pressure.
Call
From the Main Menu select [Load] tab > [Type : Static Loads] > [Lateral] group > [Earth Pressure] > [Parameters of Soil Properties]
Input
Soil Properties Name
Define soil property name.
Soil Level
Set the level (GCS Z-axis) of ground, footing bottom, and bedrock
Ground Level :Level of ground surface
Bottom Level of Footing : Level of footing bottom
Bedrock Level : Level of Bedrock
Soil Parameters
Soil characteristics can be specified.
Height : soil layer thickness
No.of Copies : It can be defined by considering the number of repetitions for which the thickness is set.
Use N Value : Use N value instead of internal friction angle (Angle). If N is entered, the friction angle is calculated and applied using the following formula.
(The formula suggested by Dunham: when the particle size is poor and the earth particles are round)
Level : The location of the soil layer, automatically calculated by considering the soil thickness from the ground level entered in the soil levels.
Angle : Internal friction angle of soil (degree)
Density : Unit volume weight of soil.
It must follow the soil quality test value, but if there is no test value, 1700~1800kg/m3 of normal soil and good quality soil can be used.
