| 摘 要： | 首先介绍了岩体体积节理数（JV）的定义，指出 JV 定义中采用节理间距或频率更为恰当。进而讨论了体积节理数计算公式的适用范围，研究表明：该公式仅适用于岩体内分布有不多于3组贯通性正交节理的情况，而一般情况下计算结果偏大。然后，通过体积、连通率修正，使(JV)可适用于贯通性节理岩体和断续节理岩体，客观准确地反映工程岩体完整程度。 |
| 关 键 词： | 节理岩体 贯通性节理 断续节理 体积节理数 |

| Abstract: | The definition of volumetric joint count(J V) for rock mass is introduced firstly and the indexes of joint set spacing or frequency are more suitable to the definition of J V.The formula's suitability of volumetric joint count(J V) for rock mass is discussed and the study result indicates that this formula is only suit for rock mass with one through joint set or two to three perpendicularly through joint sets.And the result with this formula is usually bigger.After volumetric and joint persistence ratio mod... |
| Keywords: | jointed rock mass through joint intermittent joint volumetric joint count |
