Mechanical Performance Degradation and Microstructural Evolution of Grout-Reinforced Fractured Diorite Under High Temperature and Acidic Corrosion Coupling

The long-term stability of grout-reinforced fractured rock masses in acidic groundwater environments after tunnel fires is critical for the safe operation of underground engineering. In this study, grouting reinforcement tests were performed on fractured diorite specimens using a high-strength fast-...
