摘要

对软岩(砂浆模拟材料)进行了应变速率范围为10-5~101s-1的动单轴压缩实验。实验结果表明，试样的抗压强度随应变速率的增加有较明显的增加趋势，增加幅度大于硬岩；试样的弹性模量以及泊松比随着应变速率的增加均有增加的趋势，但幅度小于强度的增加幅度。并根据不同应变速率下试样破裂面的SEM实验结果，初步地分析了软岩动态力学特性机理。

Abstract

The experimental study on soft rock (analogized with mortar) under dynamic uniaxial compression at the strain rates from 10-5 to 101 s-1 has been carried out. It is indicated that the compressive strength of the soft rock increases with the increasing strain rate; and the rising rates are higher than that of hard rock. The Young’s modulus 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

based on the SEM results

the mechanism of the strain rate effect of the soft rock is primarily analyzed.
