抄録

Dilatancy of rock is interpreted as the accumulation of microscopic failures induced by deviatric stress, based on a great number of experiment and observation. However, the ability to express the quantitative relationship between stress condition and dilatant strain caused by such micro-scopic failure requires more research. In this paper, on the assumption that open cracks grow in consequence of failures, the equations which describe the stress-strain relationship were derived by applying the fracture mechanics.<br>The conclusions are summarized as follows;<br>(1) Secondary cracks generated by deviatric stress grow almost in the direction of maximum compressive stress.<br>(2) Dilatant strain caused by the crack growth is in inverse proportion to minimum compressive stress.
