结果表明，含有预制裂纹的红砂岩的损伤演化和裂纹的扩展受到预制裂纹的影响，破坏裂纹从预制裂纹尖端起裂，并且最终破坏发生于含有最大预制裂纹的层面。 | | 4. | 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。 | | 5. | 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。 | | 6. | 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。 |
