THEORETICAL STUDY OF GROUND MOTION PRODUCED BY NUCLEAR BLASTS
Abstract
Free-field ground motions for use in the design of underground protective structures are studied. Two-dimensional motion of an elastic half-plane under an exponentially decaying normal load traveling at constant velocity along the boundary is determined analytically and the results are presented graphically. Analytic expressions in integral form are obtained for three-dimensional axisymmetric motion of an initially quiescent homogeneous isotropic elastic half-space underAN ARBITRARY AXISYMMETRIC TIME-DEPENDENT NORMAL LOADING, AND THESE EXPRESSIONS ARE UTILIZED FOR THE SPECIAL CASES OF A CONCENTRATED NORMAL POINT LOAD AND A UNIFORM CONCENTRATED NORMAL RING LOAD SUDDENLY APPLIED AND THEREAFTER MAINTAINED AT A FIXED POSITION ON THE PLANE BOUNDARY. Analytic expressions in integral form are obtained for the three-dimensional axisymmetric motion of a homogeneous isotropic visco-elastic half-space under identical conditions as for the elastic case.
