| 摘 要： | 通过对单轴、三轴软硬互层岩体在不同应力水平和 加载路径下的蠕变试验结果分析，研究了应力状态及加载方式对软硬互层岩体时间相关性特征的影响，利用软件FLAC3D对所建立的计算模型进行了三维粘弹塑性数值模拟。结果表明：对于所研究的软硬相间复合岩体，在施加荷载相同的情况下，软岩层数、软岩埋深以及倾斜角度，对岩体蠕变变形和塑性区均有不同程度的影响。

| Abstract: | The effects of stress level and loading path on rheologic behaviors of alternating distribution of soft and hard rock layers are investigated with triaxial and uniaxial experiments. By using the simulated software FLAC^3D, the established model is analyzed with the method of 3-D visco-elasto-plastic numerical simulation. The results show that, under the same exerting loading level, the deformation and volume of plastic zone of rock mass will be increased with the increase of the number of layers, embedded depths and declination of soft rock. |
