采用RFPA2D软件对6组不同高径比的岩石试样进行单轴压缩下的数值模拟,研究了尺寸效应对岩石强度及其破坏过程中声发射特性的影响,指出岩石的破坏过程大致可以分为五个阶段。
採用RFPA2D軟件對6組不同高徑比的巖石試樣進行單軸壓縮下的數值模擬,研究瞭呎吋效應對巖石彊度及其破壞過程中聲髮射特性的影響,指齣巖石的破壞過程大緻可以分為五箇階段。

This paper used the RFPA2D software made numerical simulation under single axial compression to rock sample with 6 groups of differ-ent high diameter ratio,researched the influence of size effect to rock strength and its acoustic emission characteristics in failure process,pointed out that the rock failure process could be divided into five stages.
