Elastic modulli of porous rocks was calculated from the velocity of elastic waves in regard to changing water content. (1) When the rock specimens are saturated by water, Young's modulus measured by pulse method indicated little change from dry state except loosely cemented sandstones of Tertiary rocks but the modulus calculated by resonance frequency method indicated a little decrement. (2) In most rocks saturated by water, shear modulus indicated 1〜7 percents decrement of room dry state, and the modulus of loosely cemented sandstones of Tertiary rocks indicated 70 percents decrement. (3) Comparison with the three Poisson's ratios calculated using the data of pulse and resonance frequency method showed following order of magnitude ; ν_<PR>≒ν_P>ν_R.
