中文摘要：
以金川有色金属公司Ⅱ矿区深部岩石为研究对象,实验采用分级增量循环加卸载方式进行,根据蠕变实验所得的曲线,按照可恢复的瞬时弹性应变、滞后黏弹性应变、不可恢复的瞬时塑性应变与黏塑性应变进行数据分析,得出深部岩石的黏弹塑性的变形特性。在对数据进行深入的分析和对比后,引入改进的西原正夫模型来研究该深部岩石的黏弹塑性的变形特性。研究结果表明：改进的西原正夫模型的理论曲线与岩石实验所得的蠕变曲线能较好地吻合,说明该模型可以较好的模拟金川Ⅱ矿区深部岩石的蠕变变形特性。
英文摘要：
The creep experiments were conducted by adopting multi-step incremental cycling loading and unloading method and using rock samples collected in Jinchuan No.2 mining area.According to the experimental creep curve,data of experiments were processed according to instant elastic strain,visco-elastic-plastic strain,instant plastic stain and visco-plastic stain,respectively.Deformation feature of visco-elastic-plastic rock in depth level was derived.Modified K-B model was adopted to analyse the mentioned deformation feature.The results show that the curve of modified K-B model well agrees with that of creep rock samples.The adopted modified K-B model can well describe the creep properties.
