The section of this report devoted to the control of slides
serves to illustrate the more typical situation of a movement, that
is not subject to a theoretical analysis. The great majority of
slides that occur in natural ground pass through complex soil stratifications that do not permit the simplifying assumptions needed for
the various methods of mathematical and graphical analysis, In these
cases, the procedures for the control and stabilization of the moving
material depend exclusively on the characteristics of the particular
location, Each slide is a separate problem whose solution is not
necessarily similar to any other.
The control section of this report has presented a summary of
the various methods for the field control of slides that may he used,
The choice of the applicable method is made only after extensive
study of the nature of the particular slide, The more common control
procedures have been illustrated by reference to the case histories
of actual slides that have been successfully controlled.
