As part of port expansion project, a temporary vertical cut is to be made in a submerged clay deposit. A cross section and soil parameters are shown below. (Note: if needed, you can use a single wedge failure mechanism with an inclination of 45° for the failure surface) Clay c = 450 psf, o = 0° y = 100 pcf H. Note: the slope is submerged a) How deep can you make the cut with a factor of safety of = 1.5 for temporary construction? b) If the project was abandoned after the vertical cut was made, would you still expect the vertical cut to be standing 20 years? Why or why not? Support your answer with calculation.

In an anchored shoring application where you know the layering status of the soil profile, the vertical spacing of the anchors placed along the excavation depth (H) can be determined primarily according to which of the following options? a. All anchors should be positioned close to the surface as the excavation top level will be more displaced. b. It should be determined according to the slip plane. c. The top row anchor should be determined at a depth to balance the cover load, and in the vertical shoring element between two consecutive lower and upper anchors, the cantilever should be determined to prevent operation. d.

6.5 The sides of an excavation 3.0m deep in sand are to be supported by a cantilever sheet pile wall. The water table is 1.5 m below the bottom of the excavation. The sand has a saturated unit weight of 20 kN/m³, a unit weight above the water table of 17 kN/m³ and the characteristic value of o' is 36°. Using the traditional method, determine the required depth of embedment of the piling below the bottom of the excavation to give a factor of safety of 2.0 with respect to passive resistance. M
