Figure 15.21 and Figure 15.22 show details which have been adopted for Khao Laem,
Golillas Dam and Macaqua Dam.
The base of the wall is usually above full supply level and the wall is joined to the
face slab with a flexible joint, such as that shown in
Figure 15.23
. The joint should
be vertical, not normal to the plane of the slab, so that differential settlement can be
accommodated.
