| 摘 要： | 针对天然裂隙岩体等效水力隙宽确定的复杂性,利用平行板水流的立方定律及流量等效原理,推导出光滑平行板单裂隙的等效水力隙宽公式,同时对隙宽分布的频率特性进行了探讨,认为非均匀隙宽单裂隙的等效水力隙宽可近似取40%频率的隙宽,或取隙宽的几何平均值与调和平均值的算术平均值. |
| 关 键 词： | 岩体裂隙 等效水力隙宽 累积频率曲线 |

| Abstract: | It is complicated to determine the equivalent hydraulic aperture of natural fractured rock mass. This paper works out the formulae of equivalent permeable aperture of smooth and parallel single fissure based on the research works of the predecessors and the cubic law and inflow equivalent principle in parallel board. The analysis of the frequency characteristics of aperture reveals that the equivalent hydraulic aperture of the fissure with non-uniform aperture is almost equal to 40% of frequency aperture or equal to the average aperture of geometric mean and harmonic mean. |
| Keywords: | rock fissure equivalent hydraulic aperture cumulative frequency cure |
