  2. 2 ) through many numeral experiment, using the crack face ' s slant angle and azimuth angle as parameters, we found some relations between three - dimension fractal parameters and two - dimension fractal parameters in rock mass : ds = ( 1. 0 + 0. 031 ) * dl + ( 1. 0 + 0. 0395 ), ns = nl, v = 1. 5986 * ( 2 - dl ) - 3. 2935 * sin ( st ) + 3. 8263, and found a way to speculate three - dimension fractal parameters from two - dimension fractal parameters. lt is the foundation to describe the distribution laws of crack face in rock mass by the observing results through rock mass section crack, 3 ) this paper constructed the three - dimensional fractal emulation theoretical system and erected three - dimensional fractal emulation model about crack face in rock mass 4 ) a emulation system about crack face in rock mass is developed by vc + +, it includes the function to get section plane chart and section block chart from three - dimensional network chart automatically, and some of the emulation examples is given

    2 )通過大量數值試驗,以巖體裂的傾角與方位角為紐帶,分析得出了巖體裂數量三維分形分佈參數和巖體裂二維分形分佈參數的關系: d _ s = ( 1 . 0 0 . 031 ) * d _ l + 1 . 0 0 . 0395 , n _ s = * n _ 1 , = 1 . 5986 * ( 2 - d _ l ) - 3 . 2935 * sin ( st ) + 3 . 8263並提出了由二維分形幾何參數來推導三維分形幾何參數的方法。為通過巖體剖直接觀測結果,描述巖體裂分佈規律奠定了基礎。 3 )本文構建了巖體裂的三維模擬理論體系,建立了巖太原理二大學周眨d二研究生學位論文體裂的三維分形模擬模型。
  3. As the yardstick changes of crack face is following self - similarity physics law, this paper prosecuted several deep researches on the crack face in rock mass as follows : 1 ) the fractal geometry theory is used to study the characteristic of crack face number in rock mass and a research method about three - dimension fractal distribution to crack face in rock mass was brought forward. we calculate the number of crack when the position of the crack face distribution is random and the crack face ' s slant angle and azimuth angle is certain by numeral experiment, and verify that the crack face number in rock mass comforming three - dimension fractal distribution law is correct
