Sevaral significant ~reme ta rs tha t could effect inter- action in a dam-foum~s~iom sy~em ere dlscuued. Then parameters are:- (i) Fundamental periods of ~e ~ the fouDdatlon la~vlr; (2) Lateral exteve of ~he dam; (3) The material l~'operties ofT.he dam a~d the fou~ds~ion layer. Five cases are analysed to illustrate the In- fl~nce of the ~emet~rs on i~arac~ion. An inte~- action ratio Ri~ is ir~Aroduced which relates the responme of %~e dam-foum~iom sy~em st the base of %he dam I;o the free field response. The ratio D/B is also iz~Ar(~ed where D is the depth of the f~.,,~-~lon le~m~, az~ B Is the ~ of %he dam ~ec~ion. The use of theme two ratios is f~ to aid in as~ea~i~ the reel f~ analyai~ the response of the dam-fou~d~lon as a cou~le~ c~ as a de- cce~led ~ystem.
