钢纤维或复合纤维喷射混凝土具有优于普通喷射混凝土的抗开裂、抗冲击和耐疲劳等优点,被越来越多地应用于土木工程.为了研究不同纤维的掺量对混凝土基本力学性能的影响,本文对两种配方的纤维喷射(钢纤维、钢纤维+聚丙烯纤维)混凝土进行了剪切试验,并与喷射素混凝土的剪切性能进行对比分析,最终得出剪切力学性能优异并适用于隧道工程的纤维喷射混凝土.

The steel fiber or composite fiber shotcrete shotcrete has better than ordinary resistance to cracking, impact and fatigue resistance, etc., are increasingly used in civil engineering. To study the effect of different fiber content of the basic mechanical properties of concrete, two formulations paper fiber injection (steel fiber, steel fiber + polypropylene fibers) concrete shear test, and with the injection of plain concrete shear performance comparative analysis, the final results of shear excellent mechanical properties and is suitable for fiber shotcrete tunnel project.
