摘要
20世纪90年代湖南大学开启UHPC超高性能混凝土试验,初步认识到UHPC超高性能混凝土相较于常规混凝土有更为优秀的韧性与耐久性表现.以某省长益高速公路扩容工程第一合同段建设为契机,将UPHC超高性能混凝土在π型钢混组合梁结构接缝中展开实践,旨在为今后的桥梁建设带来更丰富的创造空间.
Abstract
In the 1990 s,Hunan University started UHPC ultra-high performance concrete test,which made us preliminarily realize that UHPC ultra-high performance concrete has better toughness and durability performance than conventional concrete.Taking the construction of The first Contract Section of Hunan Changyi Expressway Expansion Project as an opportunity,UPHC ultra-high performance concrete has been put into practice in the structural joints of π-type steel composite beams,aiming to bring more creative space for future bridge construction.
