Figure 5.1 below shows a cross-section of a cofferdam lined with an impermeable sheet pile wall. Take hydraulic conductivity to be 15 x 10-3 m/s and the unit weight of saturated sand to be 18.5 kN/m3. i) Estimate the seepage into the excavation and comment on the likelihood of piping occurring. ii) Determine the factor of safety (FOS) against piping. iii) Explain how and why you could increase the factor of safety against piping. 2 m 8 m 5.5 m + Figure 5.1
