摘　　要：基于近30年的研究和工程实践,UHPC在土木工程领域应用的相关标准从无到有,不断取得新进展。UHPC拥有优异的力学性能和耐久性,如何科学合理地表征这些性能并对其进行合理分级和要求,以及采用合适的试验方法测试与检验这些性能,是编制UHPC标准材料部分要完成的任务,也是制定UHPC结构设计和施工标准的基础。基于此,概要介绍了法国和瑞士标准、奥地利和美国FHWA指南中关于UHPC性能的要求和试验方法,并结合其他UHPC标准,进行了分析评述,以期为工程行业提供参考。Based on nearly 30 years of research and engineering practice,the relevant standards for the application of ultra-high performance concrete(UHPC)in the field of civil engineering have emerged from scratch and continued to make new progress.UHPC has excellent mechanical properties and durability.How to scientifically and reasonably characterize these properties,classify and require reasonably,and use appropriate methods to test and inspect these properties is the task to prepare UHPC standard materials,as well as the basis for formulating UHPC structural design and construction standards.Based on this,the requirements and testing methods for UHPC performance in French and Swiss standards,Austrian and American FHWA guidelines are summarized in this paper.And combined with other UHPC standards,an analysis and evaluation are conducted in order to provide reference for the engineering industry.
