2. Log-time curve fitting method

Try these first

1. 1.

   What is the first step in the log-time curve fitting method?

   Hint

   Think about how we measure and visualize time.

2. 2.

   Define consolidation in the context of soil mechanics.

   Hint

   Consider what happens to soil under pressure.

3. 3.

   What is the log-time curve fitting method primarily used for?

   • Analyzing traffic flow
   • Soil consolidation prediction
   • Wave pattern analysis

   Hint

   Think about the context of soil mechanics.

4. 4.

   True or False: The tangent drawn in the log-time curve fitting method helps measure the initial rate of consolidation.

   • True
   • False

   Hint

   Remember how tangents interact with curves.

5. 5.

   Given a set of dial readings at various square root times, derive the tangent and show how you would calculate the consolidation time using the log-time curve fitting method.

   Hint

   Start with calculating the slope of the tangent using rise/run.

6. 6.

   Using the given ratio of OR=1.15OQ, if OQ is measured as 3 units, what will be the measurement of OR, and how does this affect the positioning of point S?

   Hint

   Multiply directly, then plot where OR connects with the curve.
