摘　　要：超高性能混凝土(UHPC)是一种新型水泥基复合材料,有极高的抗压强度,掺入纤维后材料的抗拉性能、韧性显著提高,并具有优良的抗冲击、抗疲劳性能,材料还具有极佳的耐久性,在建筑工程领域有很好的应用前景。本文以国际和国内相关的研究成果为基础,介绍了UHPC的制备原理、制备技术和基本性能,并对UHPC构件的设计方法进行了介绍,为UHPC的应用与发展提供依据与参考。Ultra-high performance concrete （UHPC） is a new kind of cementitious material with good application future in civil engineering because it has ultra high compressive strength. By incorporating high volume fraction of steel fibers, it has high tensile strength and ductility, and outstanding abilities to absorb energy and resist impulsive loading. In addition, the durability of the material is excellent. Based on collecting and analyzing international and domestic research results, the preparation principles and techniques, and basic properties of UHPC were summarized, and the design method of UHPC was introduced.
