摘要
从云南省曲靖～陆良高速公路微扭剪切型钢纤维增强混凝土试验路面中纤维分布的实际情况出发 ,应用计算机图像技术 ,编制钢纤维分布细观几何参数的计算机测试系统 ,研究了钢纤维分布的细观几何参数 ,分析了钢纤维混凝土路面中钢纤维的分布规律。依据随机数学和体视学原理 ,建立了钢纤维分布随机过程的数学模型 ,研究了钢纤维的动态转移过程。研究结果表明 ,剪切型钢纤维混凝土试验路面中钢纤维细观几何参数具有负偏斜的正态分布规律 。
On the basis of the steel fibre distribution in steel fibre reinforced concrete surface of trial pavement of Qujing Luliang Expressway Yunnan, the computer testing system for the steel fibre distribution mesoscopic geometry parameter is authorized by using digital image processing technology.Then,the mesoscopic geometry parameter of steel fibre distribution is studied and the law of steel fibre distribution analyzed.The mathematical model of stochastic processing of steel fibre distribution in reinforced concrete is established by the stochastic mathematics principle and the cubage perspective principle.The dynamic fibre transfer processing is also investigated.The results show that the mesoscopic geometry parameter of steel fibre is negative deflexion homocercal distribution.It is concluded that the distribution of steel fibre is stochastic and the proposed model is practically valid. \ \
