摘要：Highlights Critical amid climate change and rapid urbanization. Aging infrastructure, rising sea levels, and pollution strain urban areas. Smart grids reduce electricity use by 12%–15%. Self-healing concrete cuts maintenance costs by 50%–70%. Digital twins and artificial intelligence analytics reduce downtime and costs by 30%–50%.

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.

关键词：Modeling and experimental validation of boltgrout bondslip behavior for deep underground excavation support
摘要：AbstractThe stability of rock masses in deep underground excavations, such as deep tunnels, shafts, and caverns, critically depends on the mechanical performance of bolt–grout reinforcement systems. In high-stress and complex geological environments, the interfacial bond–slip behavior between bolts and grouting materials governs the load transfer capacity and long-term reliability of the supp...

关键词：Analytical stress solution framework for lined compressed air energy storage chambers and its application to safe burial depth determination supporting effectiveness evaluation
摘要：Highlights A novel closed-form solution analytically describes the stress distribution in lined compressed air energy storage caverns under coupled asymmetric geostress and high internal pressure. A plasticity criterion-based iterative algorithm determines the minimum safe burial depth while quantifying lining material/thickness impacts. Ultra-high-performance concrete linings demonstrate dual-functional superiority: tensile strain below damage threshold and lower gas permeability.

关键词：Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining
摘要：AbstractIn the Jurassic coal-bearing strata of western China, thick soft protection layers (TSPLs) are widespread and play a key role in controlling roof water inrush hazards. Understanding their time-dependent deformation and failure mechanisms is essential for hazard prevention. This study combines laboratory creep tests, mechanical modeling, and numerical simulations to investigate the fract...
