| 摘 要： | 本文在XPK—6型矿相显微镜下,对单一裂纹,双裂纹和三裂纹试件的断裂过程进行了比较详细的观察分析。试验结果表明:不同数量,间距和排列方式的裂纹,对试件的断裂过程有不同的影响,三裂纹试件的裂纹开裂传播和扩展过程与双裂纹试件基本相同。

| Abstract: | In this paper the fracture process of specimen,with single crack, double cracks and triple cracks is observed and analysed. The experimental results show that the fracture process of specimen is different because of the differention of the number, the distance and the type of array of cracks. And the fracture propagation of specimen with triple cracks and double cracks is foundmentally the same. |
