Soil Type

The Soil Type tab allows for the definition of soil types used in the Soil Layer page. For each soil type the following parameters can be defined:

Defining Standard Deviation Models

The uncertainty of the non-linear curves is characterized by a truncated normal distribution. The distribution is truncated with a minimum value to prevent errorneous negative values. UTSR allows the user flexibility in the definition of the standard deviation. In the simplest manner, a constant standard deviation can defined. However, the user also has access to the strain and magnitude of the property, and a variety of mathimatical functions.

In the formula for the standard deviation of the shear modulus, the following variables can be used:

Likewise, the following variables are available in the definition of the standard deviation of the damping: The following functions are available:
