通过在PFC5.0中建立具有一定级配特征的颗粒，来实现水泥混凝土或沥青混合料的三维单轴压缩模拟试验，可用来参数标定和进一步进行拓展优化。若有错误，敬请谅解！ 1.成型 思路很简单，设定一个级配曲线Table，通过x和y数值成型60*60*80mm的混凝土级配试样。生成与wall相同范围的Geometry命名为框架(Kuangjia) new set random 10001 domain extent -0.1 0.1 -0.1 0.1 -0.1 0.1 def para shijian_H = 80e-3 shijian_D = 60e-3 radius_min = 2e-3 poro = 0.2 end @para wall generate plane position [shijian_D*0.5] 0 [shijian_H*0.5] ddir 90 dip 90 wall generate plane position [-shijian_D*0.5] 0 [-shijian_H*0.5] ddir 90 dip 90 wall generate plane position 0 [shijian_D*0.5] [shijian_H*0.5] ddir 180 dip 90 wall generate plane position 0 [-shijian_D*0.5] [-shijian_H*0.5] ddir 180 dip 90 wall generate plane position 0 0 [shijian_H*0.5] ddir 0 dip 0 wall generate plane position 0
