Notes:
The present paper introduces the experimental study on soft rock (analogized with mortar)under dynamic uniaxial compression at the strain rates from 10〈sup〉〈/sup〉-5 to 10〈sup〉〈/sup〉1s〈sup〉〈/sup〉-1. It is indicated that thecompressive strength of the soft rock increase with the increasing strain rate and the rising rates arehigher than that of hard rock. The Young's moduli and Poisson's ratio of the soft rock increase with the increasing strain rate, but the rising rates are less than that of compressive strength. In addition, the mechanism of the strain rate effect of the soft rock is primarily analyzed based on the SEM results
