At the beginning, the anisotropic effect to the P-wave velocity affected by the sheeting joint in the weathered granitic rocks have become evident. (1) P-wave velocity of collected specimens showes distinctly an anisotropy in the weathering grade from nearly 0.6 km/sec to 4.0 km/sec, but an anisotropy extent of thease values. In specimens, relation of P-wave velocity between horizontal direction and vertical direction is approximated to a circle equation 2-1. (2) On the other hand, P-wave velocity in situ showes an isotropy under about 0.5 km/sec, but on anisotropy over this value. In situ, a relation of P-wave velocity between horizontal direction and vertical direction is approximated to an increasing logarithmic equation 2-2. At the next, under the consideration of an anisotropic effect, analysis of time-distance curves of mirage form has been treated. The author induced an integral equation 3-12 in order to corrected velocity profile analyzed ae an isotropic medium. This equation was induced from a reciprocal
