介绍采用新型材料超混杂纤维代替钢纤维喷射混凝土的研究，其各项物理性能与掺钢纤维混凝土相当，但喷射效果优于掺钢纤维混凝土，且成本低廉，经济效益显著，很有推广价值。
This paper introduces the research on using new type of superhybrid fiber instead of steel fiber shotcrete. Its physical properties are similar to those of steel fiber reinforced concrete, but the spraying effect is better than that of steel fiber reinforced concrete with low cost and significant economic benefit.
