Question

2. A horizontal aquifer is overlain by 36 m of saturated clay. The specific weight (unit dry weight) of clay is \( 3920 \mathrm{~N} / \mathrm{m}^{3} \) and the specific weight of water at \( 15^{\circ} \mathrm{C} \) is \( 9797 \mathrm{~N} / \mathrm{m}^{3} \). The porosity of the clay is \( 40 \% \). a) Calculate the total stress acting on the top of the aquifer.

Step 1

Given: Specific weight of clay, \( \gamma_{\text{clay}} = 3920 \, \text{N/m}^3 \) Height of clay layer, \( h = 36 \, \text{m} \) Porosity of clay, \( n = 40\% = 0.4 \) The total weight of the overlying clay layer can be calculated as: \( W_{\text{clay}} = Show more…
