Abstract
Foundation treatment is a critical component in construction engineering, and grouting reinforcement technology, as an effective method for foundation improvement, has been widely applied in the management of weak foundations. To investigate the effectiveness of grouting reinforcement technology under various geological conditions, this study, based on multiple engineering cases, systematically analyzed the influence of factors such as grouting materials, pressure parameters, and construction techniques on reinforcement outcomes through a combination of field tests and numerical simulations. The research demonstrates that cement-based grouting materials exhibit excellent filling and bonding properties, effectively enhancing foundation bearing capacity; high-pressure jet grouting significantly increases the strength of composite foundations and enlarges the deformation modulus; double-liquid grouting technology can achieve rapid solidification, making it suitable for emergency treatments. An innovation of this study lies in the introduction of a multi-physics coupling model, which, combined with actual engineering data, established a predictive evaluation system for grouting reinforcement effects, achieving precise quantification of the grouting process and reinforcement outcomes. The results indicate that appropriate selection of grouting parameters and optimization of construction techniques are crucial for ensuring reinforcement effectiveness. This technology performs outstandingly under complex geological conditions, providing theoretical basis and technical support for similar projects, and holds significant engineering application value.
