950. ABSTRACT
This is an analytical study of the loading and
response of various types of dams when they are
subjected to underwater or surface detonations.tThe
objectives of the project to establish the physical
vulnerability of dams are not only to collect
information defining the loading under such conditions
and to develop suitable methods for computing the
response, but also to compute the response of several of
the more common types of concrete gravity dams.
Contained in the study is a summary of the data now
available on phenomena associated with shallow ater
explosions, and of the methods whereby this data has
been used to predict the loading imposed on the dams.
Also discussed are methods used for computing the
response of gravity dams both prior to and after
cracking. The application of these computational
procedures and loading data have been illustrated by
using a medium high-bead straight gravity dam as an
example. Several conclusions pertaining to the blast
effects on this type of dam are presented.
