Measurements and visual observations made during the Hardtank II series of underground shots are used as a basis for the shock-resistant design of protective measures for cavities in rock and qualitative predicantion of permanent displacements in rock due to nuclear detenations. Vibration measurements on blast-resistant construction in soil were used in the shock- resistant design. With varying soil cover, the compressive mode predominated in arch structures and a mass of soil apparently acted with the structure that varied in magnitude in inverse fashion with two depths of cover. Underground structural harmonic response theories were in part verified for some structures, al though the absence of an appreciable flexural mode in buried arch structures was significant. (auth)
