钢纤维是种新型的复合材料，它是将短而细的钢纤维均匀分散在小骨料为基体的混凝土或砂浆中，构成一种均匀分布的非连续的配筋中体．从而提高混凝土的抗拉强度，抗裂，抗冲，耐磨性，龙凤山水库消险施工中．在水库电站输水洞底拱，溢洪道一级消力池底板，西山灌溉洞出口消力池边墙的补强加固中．应用了钢纤维混凝土新技术，经工程运行实践证明．达到了设计的预期目的． Steel fiber is a new kind of composite material. It is to disperse short and thin steel fibers uniformly in small aggregate concrete or mortar to form a uniformly distributed non-continuous reinforced body. Thereby increasing the tensile strength of concrete, cracking, impact resistance, wear resistance, Longfengshan reservoir construction in danger. In the reservoir hydropower station tunnel arch, spillway a tank floor, Xishan Irrigation Cave exit Stilling wall reinforcement in the reinforcement. The application of new technology of steel fiber reinforced concrete, the engineering practice proved. Reached the design of the intended purpose.
