Midterm Exam Subject: Deep Excavation Exercise 1: An anchored sheet-pile bulkhead is shown in Figure P14.6. Let L, 4 m L₂ = 9 m, 4,2 m. y = 17 kN/m³. Ya 19 kN/m³, and '= 34°. a. Calculate the theoretical value of the depth of embedment, D. b. Draw the pressure distribution diagram. c. Determine the anchor force per unit length of the wall. Use the free earth-support method. Water table D Anchor Sand c' = 0 Y Exercise 2: In exercise 1 assume that Dactual = 1.3Dtheory. Sand Yat c'=0 Sand You |c²=0 Figure P14.6 a. Determine the theoretical maximum moment. b. Using Row's moment reduction technique, choose a sheet-pile section. For the sheet pile given: E = 210 x 10³ MN/m² and all = 210000 kN/m². Assume the sand is loose sand.
