• The aim of this work is , using the experimental acoustic emission ( ae ) technique , to study the effect of stress on rock fracture , the changes of some values before rock failure and the influence of cracking in rock on fracture
  本文利用实验室声发射( acousticemission ，简称ae )技术，讨论了应力方式对岩石破裂的影响、岩石破裂过程中一些物理量的变化和预制裂纹系对岩石破裂的影响。
• The following results were found , i . e . , the water ratio affects obviously the acoustic wave velocity of rock sample ; the wave velocity is higher in saturated rock samples than in unsaturated ones ; and it decreases gradually with the strain of samples during uniaxial compression ; and also with the lengthening holding time at 160 ; when heating the samples the acoustic wave velocity increases slightly in initial stage and comes to the peak value at 60 , then decreases gradually with increasing temperature ; meantime , there is a certain temperature effect on rock samples size
  实验发现含水率对波速影响比较大，饱和岩样的声波传播速度高于不饱和岩样的声波传播速度；人工预制裂纹对声波传播速度影响不大；单轴压缩条件下，声波传播速度随应变增加逐渐降低；在同一温度( 160 )下，波速随保温时间的增加而逐渐降低；在对岩样逐渐加热情况下，初始加热阶段波速略有升高，当温度达到60时，岩样波速达到峰值，之后随着温度继续升高其波速逐渐下降；波速随温度变化具有一定的尺寸效应。
• Barrier cracks cannot stop the extending of a fracture , and the strength of the sample is reduced by almost one magnitude because of the existing barrier cracks . there are great differences of ae distribution between specimens with non - penetrate crack and specimens with penetrate crack . as for penetrate crack , ae occurs near the two end of the crack , and for non - penetrate crack , crack , ae occurs near the two end of the crack , and for non - penetrate crack , ae occurs near the front edge of crack , which can be explained well by the theory of 3 - d fracture ; ae distribution near the outer part of collinear crack is similar with that of the end of penetrate crack , and inner part of collinear cracks will run - through with high loads
  关于预制裂纹系对岩石破裂的影响，集中讨论了：空障碍体构造不能阻止主裂纹的扩展，反而会使岩石的破裂强度降低近一个量级；由于构造的不同，非穿透切口样品和穿透切口样品的声发射空间分布特点有本质区别，穿透切口样品的微破裂在切口两端发育，而非穿透切口样品的微破裂在切口两端之间切口前缘处发育，这用三维破裂理论可以很好地解释；含共线构造的岩石，裂纹外端的声发射分布与单裂纹构造中裂纹端部的声发射分布相似，裂纹内端声发射有密集分布，在应力达到一定水平时，内端部发生错断，而不是贯通。
