高速铁路桥面防水层玻璃纤维混凝土配合比设计与优化

Design and Optimization of Mix Ratio of Glass Fiber Reinforced Concrete for Waterproof Layer on Bridge Deck of High-speed Railway

通过对玻璃纤维混凝土原材料技术指标研究、配合比试配、混凝土各项性能测试以及线外试验的施工,分析桥面防水混凝土各类缺陷的形成原因,提出对应改进措施,合理优化施工配合比,为京沈客专桥面防水玻璃纤维混凝土施工提供技术支持,同时对同类工程施工具有十分有益的借鉴作用。

By studying the technical index of raw materials of glass fiber reinforced concrete,matching test,concrete performance test and construction of off-line test,the causes of various defects of bridge deck waterproof concrete are analyzed,and the corresponding improvement measures and rational optimization of construction mix ratio are put forward to provide technical support for the construction of waterproofing glass fiber reinforced concrete on the special deck of Beijing-Shenyang,which provides a beneficial reference for the construction of similar projects.
