Abstract Tunnel water burst is among the common severe geological hazards in deep buried tunnel projects in China and throughout the world. Asphalt grouting is an effective method to block seepage channels in macroporous strata under the condition of flowing water, but it has defects such as a high heating temperature, complex high-temperature construction technology, and poor controllability during the grouting process. A type of “water-in-oil” low-thermal asphalt was developed in this study. It can cool and solidify and not be diluted when encountering water, and its construction temperature can be below 80°C. Experimental research on the physical and mechanical properties of the low-thermal asphalt leakage-blocking material was completed, including proportion experiments, fluidity, sensitivity to temperature, one- and two-dimensional indoor diffusion experiments, and impact experiments, which presented its physical and mechanical properties and can provide guidance for the application of the material in site projects.

一种用于堵漏注浆的低热沥青材料的研制与试验研究

摘要 隧道突水是国内外深埋隧道工程常见的严重地质灾害之一。沥青灌浆是在流水条件下封堵大孔地层渗流通道的有效方法，但存在加热温度高、高温施工工艺复杂、灌浆过程可控性差等缺陷。本研究开发了一种“油包水”低热沥青。遇水可冷却固化，不稀释，施工温度可在80℃以下。完成了低热沥青堵漏材料物理力学性能试验研究，包括配比试验、流动性、温度敏感性、
