内容記述(抄録等)Taking the value of an increase of specific surface area ΔS as a quantity expressing the degree of grain crushing of a particulate material subjected to high stresses, a relationship is investigated between ΔS and shear properties of saturated Toyoura sand at a high confining pressure, up to 500kg/sq. cm. An experimental equation relating ΔS to the mean effective stress at failure, p_&fnof; is presented in the form : ΔS=a log_<10> (p_&fnof;/b), where a and b are constants. A linear relation is also found between ΔS and F_<74>, the weight per cent of a fraction finer than 74 micron to the total sample weight. Thus, the relation curve between F_<74> and logarithm of p_&fnof; has the same pattern with the relation curve between ΔS and logarithm of p_&fnof;. On the other hand, comparing the relation curve of F_<74> and logarithm of p_&fnof; of the Toyoura sand with those of a dry limestone sand and a dry quartz sand, on which a number of high pressure triaxial tests were made by Lo and Roy, it is shown that these three curves are approximately parallel to each other. Hence, it can be pressumed that the curves of ΔS and logarithm of p_&fnof; of these three materials, and probably of any particulate materials, will have approximately the same value of slope, that is a ≒ 2100. It is suggested that there exists a method to estimate easily the value of ΔS during shear test, as a function of mean effective stress.
