摘　　要：通过实验和分析指出岩石破坏断口表面粗糙度曲线具有自相似分形特征，提出了分数维值与岩石微观破坏机制的对应关系，判明了拉西瓦地下洞室岩爆为拉破坏机制。The microtest of granite indicates that the self-similarity fractal character exists on rock surface,and the relation between rock surface fractal and the micromechanism of rock failure is found.The microtensil failure mechanism is given for the Laxiwa rockburst in Laxiwa underground cavern.
