Abstract

To address the issue of cracks appearing in the side walls and arches of a tunnel in Xinjiang after the formwork removal of the secondary lining, a comprehensive site investigation was conducted. The causes of the cracks were analyzed based on geological conditions, engineering design, construction, and concrete shrinkage. A method involving the installation of a geotextile stress absorption layer between the primary support and the secondary lining was proposed based on the actual site conditions. This method was tested on site and analyzed through numerical simulation. The results indicated a delayed occurrence and significant reduction in the number of cracks. The type of cracks transitioned predominantly from circumferential to longitudinal, and the crack lengths were reduced to between 0.2 m and 1.7 m. There was a notable improvement in the stress distribution within the lining structure, enhancing the safety of the secondary lining. This study provides insights that can be applied to optimize construction practices, quality management, and cost control in tunnel engineering.
