关键词：Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage
摘要：Highlights Studying the fracture characteristics and mechanical properties of rock mass joints before and after a high-temperature filling is of great significance for the restoration of buildings and fractured rock mass after a fire. 600°C is the threshold temperature for significant changes in fracture toughness and thermal damage of gabbro samples. In contrast to the unfilled sample, the filled gabbro sample constitutes a unified whole, which is influenced by the pressure resulting from the interaction of the filling cement and the sample. The findings presented in this study provide theoretical guidance for the evaluation of fracture damage of rocks under different loading methods and have application value for the stability of nodular fracture filling in underground engineering.

摘要：Highlights This study investigates how curing regimes influence the behavior of biocemented underground rock masses. Biopolymer-modified enzymatic precipitation boosts stiffness (+187%) and strength (+210%) in treated rock specimens. Biocementation curing at low temperatures yields greater rock reinforcement than high-temperature curing. Biopolymer addition enhances temperature sensitivity in biocementation performance. Modulus ratio is more affected by biocementation type than by curing temperature in biocemented rocks.
