| 摘 要： | 利用块体理论和概率分析理论，建立了同时考虑节理面间距和延展性随机特性的情况下构成块体体积的理论公式，据此分析了节理间距、延展性随机特性与构成块体体积的关系，进而得到了具有实用价值的计算公式，该公式结合可动块体分析方法，可以有效地解决赤平投影难以计算小型结构面构成块体体积的问题。工程实例表明，该公式具有实用性和应用前景。

| Abstract: | A new probability formula of block volume considering randomness of spacing and extension of joint planes is established by means of block theory and probability analysis. The relationship among spacing, extension and block volume is analyzed according to the formula. The traditional hemispheric projection method handled quantification index of block volumes is conquered; and the index can be obtained soundly by the formula. The applying prospects and adaptation of the formula are shown by project examples. |

| Keywords: | spacing of joint plane trace length of joint plane block volume probability analysis |
