| 摘 要： | 为进行开级配沥青碎石细观力学分析,研究了开级配沥青碎石随机凸多边形集料模型生成方法.为使模型更加逼真,生成过程更加高效,考虑孔隙的模拟,用面积控制集料颗粒的投放,利用蒙特卡罗方法生成二维随机圆形集料模型,引入一系列预判条件改进延凸公式和基块体的生成方法,改进侵入和相交判断方法,并给出2块体相交判断方法,通过延凸,生成二...

| Abstract: | For meso-mechanical analysis of open-graded asphalt macadam,the method of producing random convex polygon aggregate structure model of open-graded asphalt macadam was studied.To make the model more realistic and the generation process more efficient,considered simulation of the voids,the area was used to control throwing aggregate particles into the model,2D random circular aggregate structure model was then produced by Monte-Carlo method,a series of prejudgment conditions was used to improve the formula to... |
