VolumeMass 
An important component of SVSOILS is the ability to calculate basic volumemass properties once any three volumemass properties are known. The calculation is done by rearranging the equations describing the volumemass properties of an unsaturated soil. Once any three volumemass properties are known, the geotechnical engineer can “lockin” these properties. The “lockin” indicates that the properties are fixed (e.g., measured) and should not be changed during further calculations. The “lockin” procedure is necessary to ensure data integrity. The Calculate button can then be selected for the calculation of the remaining volumemass properties.
Category: The Category menu item is used to select either soil or tailings material. Soil is selected by default in the software. The user can select tailings to add and calculate additional properties related to oil sands tailings.
Export: The Export menu item is used to copy or export the volumemass results. Graph: The Graph menu item contains the various graphs in which the volumemass state can be represented.
An example of the calculation of volumemass properties is shown below. A soil is obtained and the properties are listed as follows:
The above properties are entered into the appropriate fields under the VolumeMass dialog and “lockedin” by clicking on the check boxes to the right of the soil volumemass properties. Selecting the Calculate button calculates the remaining soil properties:
SVSOILS contains an algorithm which allows the calculation of remaining volumemass properties based on almost any combination of three initial properties. The software will inform the user if a particular combination of volumemass properties will not allow calculation of the remaining properties. If the calculation of volumemass insitu properties is successful, the word, "successful" appears at the bottom of the dialog. It is then possible to search the database based on the VolumeMass Completed field to search for all soils on which the calculation algorithm has been run.
