The water table lies at a depth of 3 m below the ground level at a site
Question:
The water table lies at a depth of 3 m below the ground level at a site that consists entirely of sands. A 7 m deep excavation is to be made with the use of anchored sheet piles to support the excavation. The tie rod of the anchor will be placed 1 m below the ground, with horizontal spacing of the tie rods being 3 m. The unit weights of the sand above and below the water table are 17.0 kN/m3 and 20.0 kN/m3, respectively. The friction angle of the sand is 35°.
a. How deep would you drive the sheet pile, allowing a factor of safety of 1.5 on the passive resistance?
b. What is the load on the tie rods? Use the simplified approach described in Section 18.10.
