SUMMARY
This article will discuss the calculations used in the Consolidation Undrained Saturation phase of testing. Calculations conform to the ASTM standard for this test.
SOLUTION
Cell Pressure [CP] - Value recorded or entered by the user.
Back Pressure [BP] - Value recorded or entered by the user.
Pore Pressure [PP] - Value recorded or entered by the user.
Volume [V] - Value recorded or entered by the user.
Valve State - Valve state of Pore Pressure. User selected value of Open or Closed. Should follow a sequence of Open Closed Closed. The B Value will be calculated where index modules 3 = 0 (evenly divisible by 3 excluding index 0).
Change Cell Pressure [CCP] - CCP = Current recorded cell pressure - CP @ index 0.
Change Back Pressure [CBP] - CBP = Current recorded back pressure - BP @ index 0.
Change Pore Pressure [CPP] - CPP = Current recorded pore pressure - PP @ index 0.
Change Volume [CV] - CV = Current recorded volume - V @ index 0.
B Value [BV] = CPP / CCP
