PROBLEM 1
A section of a dam constructed from a clay is shown in
Fig 1. The dam is supported on 10 m of sandy clay with kx =1.2
x 10-5 cm/s and kz = 2 x 10-5 cm/s and a saturated unit weight
of 17.8 kN/m3. Below the sandy clay is a thick layer of
impervious clay. The upstream and downstream slopes are
1(V):2(H).
2/ 12
(a) Draw the flow net under the dam.
(b) Determine the porewater pressure
distribution at the base of the dam.
(c) Calculate the resultant uplift force and its location
from the upstream face of the
dam.
