摘　　要：通过对一定掺量纤维混凝土试件和普通混凝土试件的抗渗性试验研究,发现掺入体积掺量0.15%的聚丙烯纤维的混凝土抗渗性有明显提高。最后以断裂力学为基础,对纤维混凝土的抗渗性从物理机理和断裂力学机理进行了分析。Through a research of an impermeability test which contains a certain amount of fiber concrete samples and plain concrete ones,the impermeability of the polypropylene fibre(0.15% volume occupied) concrete has been improved obviously.Then,according to fracture mechanics,the impermeability of fibre concrete is discussed from 2 aspects of physics and fracture mechanics mechanisms.
