摘要:
针对目前我国隧道衬砌出现的充填不密实、背后存在空洞、局部厚度不足、存在潜在的初期开裂等问题,而有关衬砌混凝土的研究文献几乎没有,大家好像习以为常。介绍日本采用的中流动性衬砌混凝土,介绍其基本观点、特征、决定其配比的基准、设计基准强度、施工、现场试验、现场应用及应用效果等,以引起大家的关注。提出对传统的方法要针对问题逐步改善,也要结合隧道衬砌混凝土的特点,研究开发适用于隧道衬砌性能、能够消除可能存在潜在缺陷的衬砌混凝土。
关键词: 隧道, 矿山法, 中流动性衬砌混凝土
Abstract:
The tunnel lining in China has many problems, such as uncompacted filling, hollows behind lining, local inadequate thickness and potential primary support cracks; and there is any related reference. The application of medium fluidity lining concrete in Japan is introduced in terms of basic concept, characteristics, principle for mixing proportions, design basic strength, construction, site testing, site application and application effect. The author suggests that the feasible lining concrete should be studied and developed.
Key words: tunnel, mining method, medium fluidity lining concrete
