Problem \#1: Compaction ( 20 points) The results of a Standard Compaction test are shown: a. Draw the compaction curve. b. Determine the Maximum dry unit weight and OMC for this soil. Show in graph. c. What is the dry unit weight at \( 95 \% \) of maximum dry unit weight. Show in graph. d. For \( 0.95 \gamma_{\mathrm{dry}}(\max ) \), what is the possible range of \( \omega \). Show in graph. Problem \#2 Consolidation Settlement ( 20 points) Calculate the settlement of the \( 15-\mathrm{ft} \) clay layer that will result from the load carried by the square foundation \( (12 \mathrm{ft} \times 12 \mathrm{ft} \) ), as shown. Calculate: a. The increase of effective pressure (effective stress) in the clay, \( \Delta \sigma \), caused by adding the foundation. Obtain results in \( \mathrm{kips} / \mathrm{ft}^{2} \) and \( \mathrm{lb} / \mathrm{ft}^{2} \) (5 points) \( \Delta \sigma= \) \( k i p s / \mathrm{ft}^{2}= \) \( \mathrm{lb} / \mathrm{ft}^{2} \) b. Compute the effective stress, \( \sigma^{\prime} \), in-situ condition, in the middle of the clay strata. c. Obtain the primary settlement, \( \mathbf{S}_{\mathbf{c}} \). in the clay, Obtain results in \( \mathrm{ft} \) and inches, (10 points) \[ \mathrm{S}_{\mathrm{c}}= \] \[ t= \] inches Problem \#3: Consolidation Settlement Curve ( 20 points) The following consolidation curve is obtained from a construction site. Estimate the following values: Show in graph all results with their specific values. Do not forget unit: a. Stage 1: Initiol or Elastic settlement, Se b. Stage 2: Primary consolidation settlement, sc = c. Stage 3: Secondary consolidation settlement, Ss = d. Total Settlement, ST = e. Approximate time for stage of Primary consolidation = Problem \#4: Subsoil Exploration (20 points) a. First, complete the column for \( \mathrm{N} \)-value. Show procedures.
