| 摘 要： | 通过对松散岩块压实试验研究，得到了变形模量与轴向应力、轴向应变的相关性规律。试验结果表明：松散岩块的切线模量与轴向应力间呈指数关系，并随其颗粒粒径和岩性不同而变化；而其割线模量与轴向应力则呈线性关系；松散岩块的切线模量和割线模量均与轴向应地指数相关性。研究结果对松散岩块压实变形机理分析具有重要价值。

| Abstract: | Through the experimental research on the compaction of friable rock block, the relationship among deformation modulus, axial stress and strain were obtained. The result of this experiment reveals that the tangential modulus is exponential with axial stress, and varies with rock block size and rock property. The secant modulus is linear with axial stress. Both the tangential modulus and secant modulus are exponential with axial strain. The conclusion of this research is valuable to analysis of deformation mechanism of friable rock compaction. |
