5 . based on longtan project, temperature control and crack prevention of a typical overflow section block of the high rcc gravity dam is studied as a case study 以“十?五”國家電力公司科技攻關(guān)項目為背景,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)通過大量數(shù)值試驗,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=(1.00.031)*d_l+1.00.0395,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)來推導(dǎo)三維分形幾何參數(shù)的方法。為通過巖體剖面裂縫直接觀測結(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。
