Abstract: As an important transportation component, the construction of highway bridges and tunnels plays an important role in the country’s socio-economic development. With the construction of bridges and tunnels, while the number of projects has significantly increased, there have also been situations of uneven settlement, cracks and other hazards after the operation. These potential safety hazards greatly affect the normal use of highway bridges and tunnels. In order to improve the construction technology level and ensure construction quality, grouting method has played an important role in the prevention and control of diseases in bridge and tunnel engineering. This article analyzes the technical content and specific measures of the grouting method commonly used in the construction of highway bridges and tunnels from multiple perspectives. It summarizes the theory and experience of grouting method under different working conditions, providing reference for improving the quality of bridges and tunnels.

Key words: Grouting Method, Highway Bridge, Tunnel Construction
