摘　　要：为减少雨水丰富地区路面结构的水损坏和车辙病害,对刚性聚合纤维多孔混凝土的配合比设计、成型工艺、透水性、强度相关性能进行了研究,得出:刚性聚合纤维改善了混凝土的内部结构并且抑制了混凝土的干缩和开裂,增强了抗压强度,但随着掺入量增加,孔隙率和透水系数也呈增大趋势,强度提高仍需进一步改善。In order to reduce the water-caused and cartwheel-caused damages on road pavement in region with abundant rainfall, mix proportion design, forming process, water permeability and strength of rigid polymer fiber reinforced porous concrete are researched and it is found that rigid polymer fiber could obviously ameliorate the internal structure of concrete, prevent drying shrinkage and cracking of concrete and increase the pressure strength of concrete, but porosity and permeability coefficient of concrete increase when the amount of rigid polymer fiber becomes larger, so concretestrength shall be further improved.
