| 摘 要： | 拱肋高强核心混凝土施工技术难度大、质量要求高,为了确保工程施工质量,混凝土浇筑要求一次成功,混凝土可泵性是钢管混凝土浇筑成败的关键,而可泵性的关键是混凝土的配合比。针对渝湘高速公路细沙河大桥拱肋核心混凝土灌注现状,通过对核心混凝土可泵性的研究,分析钢管拱肋核心混凝土的配合比对核心混凝土成功灌注的影响,以期对钢管混凝土拱桥核心混凝土施工提供参考。

| Abstract: | The construction of high-strength core concrete for arch ribs is difficult in technique and highly required in quality,the concrete casting is required for success right one time in order to ensure construction quality.Therefore,the pumpability of concrete is critical for success of steel tube concrete casting,while the pumpability is greatly dependent on the mix proportion.This paper,aiming at the status quo of core concrete casting for arch ribs of Xishahe Bridge on Chongqing-Hunan Expressway and through ... |
