| 摘 要： | 为研究高掺量聚丙烯纤维混凝土的动力性能，本文首先配制了三种抗压强度等级的高掺量聚丙烯纤维混凝土，然后采用变截面大尺寸分离式霍普金森压杆（SHPB）对其进行试验研究。试验结果表明：高掺量聚丙烯纤维的加入使中、高强混凝土承受动载时的破坏应变增大，发挥了一定的耗能、阻裂作用，并可以改善混凝土承受动载时的破坏形态。

| Abstract: | To study the dynamic mechanical properties of polypropylene fiber reinforced concrete(PFRC) with high fiber volume,the PFRC of three kinds of strength level are prepared firstly,then are tested by split Hopkinson pressure bar(SHPB).The test results show that the polypropylene fiber of high volume can raise the failure strain of middle and high strength PFRC,consume dynamic energy,block the crack propagation and also improve the damage form of concrete bearing dynamic load. |
