With the grouting material as focus, this study aims to guarantee that the joint with tenon and mortise constructing a metro station has the necessary waterproof performance, which shall not be poorer than the mechanical properties of the concrete with joints itself, and fine structural integrity. With groutability at low-temperature and available operational time as basis, low-temperature epoxy was selected as the grouting material for the joints. The silica powder of particular particle size and mass was added for modifying the physical performance of grouting material. A series of physical and mechanical tests were conducted in an attempt to achieve the optimal particle size and mix ratio provided that costs were reduced as practically as possible. Also, the flexural capacity of the joint filled with the above grouting material was demonstrated via the combined equal-proportion joint axial bend test.

本研究以灌浆材料为重点，目的是要保证建设地铁车站的榫ten连接处具有必要的防水性能，且其防水性能应不低于连接处本身的混凝土的机械性能和良好的结构完整性。基于低温下的灌浆性和可用的操作时间作为基础，低温环氧树脂被选作接头的灌浆材料。添加具有特定粒度和质量的二氧化硅粉末以改变灌浆材料的物理性能。进行了一系列物理和机械测试，试图获得最佳的粒径和混合比，但要尽可能降低成本。也，
