以“十?五”國(guó)家電力公司科技攻關(guān)項(xiàng)目為背景，深入系統(tǒng)地進(jìn)行了龍灘高碾壓混凝土重力壩典型溢流壩段的溫控防裂研究。 - 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(guò)大量數(shù)值試驗(yàn)，以巖體裂縫面的傾角與方位角為紐帶，分析得出了巖體裂縫面數(shù)量三維分形分布參數(shù)和巖體裂縫跡線二維分形分布參數(shù)的關(guān)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并提出了由二維分形幾何參數(shù)來(lái)推導(dǎo)三維分形幾何參數(shù)的方法。為通過(guò)巖體剖面裂縫直接觀測(cè)結(jié)果，描述巖體裂縫面分布規(guī)律奠定了基礎(chǔ)。 3 )本文構(gòu)建了巖體裂縫面的三維仿真理論體系，建立了巖太原理二大學(xué)周眨d二研究生學(xué)位論文體裂縫面的三維分形仿真模型。
