Question: Flow net under a sheet pile wall is shown in the figure below. Saturated unit weight of the soil is 2 1 k N m

Flow net under a sheet pile wall is shown in the figure below. Saturated unit weight of the soil
is 21kNm3.
a) Calculate the factor of safety against heaving using the method by Terzaghi (1922) and
Harza (1935).
b) Calculate the total head, elevation head and pore water pressure at point 3 shown in the
figure below. Note that the point 3 is on the right hand side of the wall.
