对圆柱型水泥砂浆试样进行了不用围压、相同渗压下的三轴压缩试验,并对其强度特征和渗透规律进行了研究.结果表明,随着围压的增加,试样的峰值强度增大,围压提高了试样的强度;当偏应力达到临界值后,试样损伤随着偏应力的增大而增加;损伤与渗透率呈指数关系,渗透率随损伤的增大而增加.
The tests of triaxial compression tests on cylindrical cement mortar without confining pressure and same seepage pressure were carried out and the strength characteristics and infiltration rules were also studied.The results show that with the increase of confining pressure, the peak strength Increasing the confining pressure increases the strength of the specimen. When the deviatoric stress reaches the critical value, the specimen damage increases with the increasing of deviatoric stress. The damage and permeability are exponential, and the permeability increases with the increase of the damage .
