摘要
文中论述了钢纤维砼（Ｓｔｅｅｌｆｉｂｅｒｒｅｉｎｆｅｒｅｄｃｏｎｃｒｅｔｅ）基本力学性能的研究试验及其应用研究———城市道路窨井盖的试制开发，结果表明：ＳＦＲＣ的抗压、抗劈拉及抗折强度分别为素砼的１１８、２１５和１５倍，用其制作的窨井盖初裂荷载可达５０～８０ＫＮ，完全能满足国家公路路面设计规范的要求．
This paper deals with the rssearch experiments with the basic mechanics performance of steel fiber reinforced concrete (SFRC) and the research ,ofit application namely ,the development of the cover of the insection well on the urban road .The result of the esperiments shows that the comprdssive strength of SFRC is 2.15 times that of comcrete.the tensile strength of SFRC is 1.5times that of comcrete .When SFRC os used to make covers of inspection well.its initial cracl load can amount to 50～80kn.which will .completely satisfy the needs of the national standard of the road -surface design.
