摘　　要：抗裂混凝土是一种具有良好抗裂性能的混凝土,其能在混凝土硬化过程中,通过调整水泥、骨料、矿物掺合料、外加剂等材料的比例,形成具有较高抗拉、抗压强度的微观结构,从而提升混凝土的抗裂性能。文中对抗裂混凝土在暗埋地铁车站中的应用进行了详细探讨,包括抗裂混凝土的组成、配比设计、施工工艺等方面的内容,以期为类似工程提供参考。Anti cracking concrete is a type of concrete with good anti cracking performance.During the hardening process of concrete,it can form a microstructure with high tensile and compressive strength by adjusting the proportion of materials such as cement,aggregates,mineral admixtures,and admixtures,thereby improving the anti cracking performance of concrete.The article provides a detailed discussion on the application of crack resistant concrete in underground subway stations,including the composition,mix design,construction technology,and other aspects of crack resistant concrete,in order to provide reference for related projects.
