| 標(biāo)題 |
| 基于高速公路橋梁拓寬拼接的高性能混凝土的應(yīng)用研究(49 卷) |
| 英文標(biāo)題 |
| Study on application of high-performance concrete to widened expressway bridge |
| 摘要 |
| 混凝土的收縮徐變是影響橋梁拓寬拼接的控制因素之一，任何可以減小和控制收縮徐變的措施對(duì)減小新舊結(jié)構(gòu)的相互影響、降低拼接難度都是有利的。對(duì)用于拓寬梁體的具有低收縮徐變性能的混凝土和用于連接帶的微膨脹早強(qiáng)混凝土的配比設(shè)計(jì)進(jìn)行了介紹。供同類工程參考。 |
