   以“十?五”国家电力公司科技攻关项目为背景，深入系统地进行了龙滩高碾压混凝土重力坝典型溢流坝段的温控防裂研究。
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 )通过大量数值试验，以岩体裂缝面的倾角与方位角为纽带，分析得出了岩体裂缝面数量三维分形分布参数和岩体裂缝迹线二维分形分布参数的关系： 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并提出了由二维分形几何参数来推导三维分形几何参数的方法。为通过岩体剖面裂缝直接观测结果，描述岩体裂缝面分布规律奠定了基础。 3 )本文构建了岩体裂缝面的三维仿真理论体系，建立了岩太原理二大学周眨d二研究生学位论文体裂缝面的三维分形仿真模型。
