Bulk Unit Weight and Void Ratio

Unit Weight and Void Ratio may be defined in two locations and are used in the order listed:

1. CPT_POINT_MATERIAL_PROPERTIES table (Point Parameters – Bottom half). This allows you to enter a depth profile. If a depth range is missing a value, then the CPT_PROJECT_PARAMETERS table is used.
2. CPT_PROJECT_PARAMETERS table. A saturated and unsaturated unit weight must be defined, the former is applied bellow the water table and the later above the water table.

If Unit Weight and Void Ratio are not defined in either table, then the Bulk Unit Weight and Void Ratio will not be defined, and most other parameters cannot be calculated.
