Seismic response analyses of a rock cavern of an underground nuclear power plant using 3D(three-dimensional) boundary element method are conducted in order to investigate the applicability of 2D(two-dimensional) analyses and to evaluate the seismic motions of a rock cavern in case of oblique incidence of seismic wave. As the results, it was verified that responses by 2D analyses were larger and more conservative than those by 3D analyses, so 2D analyses were applicable to seismic evaluation of rock cavern. And with respect to accelerations, deformations and stresses, several phenomena peculiar to oblique incidence were observed. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
