摘　　要：基于X-ray技术,对OGFC大孔隙沥青混合料马歇尔试件进行逆向三维重构,重构后能够形象地展示OGFC混合料的内部构造,并对提取的试件内部三维连通孔隙模型进行渗流模拟,可计算出孔隙水流速度及压力流线图,同时得到水流压力场三维分布图,并计算出绝对渗流率。Reverse 3D reconstruction was used on OGFC macro-porous asphalt mixture based on X-ray technology.After reconstruction,the internal structure of OGFC mixtures can be vividly displayed,and the three-dimensional connected pore model inside the extracted specimens is simulated for seepage flow.The pore water flow velocity and pressure streamline diagram can be calculated,and the three-dimensional distribution diagram of the water flow pressure field can be obtained at the same time,thus the absolute permeability can be calculated.
