A 3 m deep excavation will be supported by a cantilever sheet pile. The foundation soil is dense sand, but it is assumed that the pile tip penetrates impermeable soil so hydrostatic pore pressure can be used. A surcharge of 10kPa is applied at the ground level.

An excavation is rapidly made on site as depicted in the Figure below. The soil wedge above the critical slip surface is divided into thirteen slices. Based on the ordinary method of slices, calculate the ratio (R/S) between the Resisting Force (R) and the Driving Force (S) for slice #3, shortly after the excavation is completed. (Acceptable tolerance = 4%). The geometry of slice #3 and the soil properties are provided in the tables below. The height of water at the middle of the slice is hw = 3.0 m. Note that the total weight of the slice is equal to the weight of the saturated soil below the water table plus the weight of the moist soil above the water table. Hint: the weight of slice #3 is 495 kN
A layer of fine sand exists over a stratum of impervious rock. The sand layer is 6.25m thick. The site is flooded and the water surface is 1.25m above the surface of the sand. It is proposed to excavate a very wide ditch through the site and to remove sand to a depth of 2.5m below the existing surface of the sand. One side of the excavation is to be supported by sheet piling driven to a depth of 4.4m below the existing surface of the sand. Draw a flow net and determine the seepage in m³/min per m length for the sand with a permeability of 0.18m/sec.
