| 摘 要： | 基于中国矿业大学深部岩土力学和地下工程国家重点实验室的MTS815岩石力学伺服实验系统，通过室内模拟环境，选取不同粒径的石灰岩进行了多组全面的渗流试验，研究了非Darcy渗流的渗透特性。给出破碎岩体的介质粒径和渗流速度对渗透系数的具体影响趋势：在一定的轴压作用下，随着颗粒直径的逐渐变大，不同岩石的渗透率逐渐增大；不同颗粒直径的岩石都有类似的压实渗透特性，随着岩石压力的逐渐增大，其厚度被逐渐压缩，渗透率逐渐变小。 |

| Abstract： | Based on the MTS815 rock mechanics servo experiment system of State Key Laboratory for Geomechanics & Deep Underground Engineering of China University of Mining & Technology, through the indoor simulated environment, many groups of comprehensive transfusion experiments of the selected limestone with different particle sizes were carried on, and the non-Darcy transfusion seepage characteristic was studied. The concrete influence tendencies are given between the medium particle size and the seepage velocity of the broken rock mass and the penetration coefficient: under certain axis presses, with particle diameter�s gradual fill-out, the penetration coefficient increases gradually; the rock with different particle diameters has the similar compaction seepage characteristic, with the rock pressure increasing gradually, its thickness reduces gradually, the penetration coefficient decreases gradually. |
