Abstract

The construction areas of both the upper water gallery of the left circular tunnel and the water gallery of the right square tunnel in the Shuangjie River gallery project in Shenzhen that pass through the parking access line of the Qianhai parking lot were numerically simulated. The ABAQUS finite element numerical simulation software was used to analyze the stress and strain of the cover and retaining pile with different sections under the design of tunnel anti-uplift protection measures. The results of the study are summarized as follows: The vertical deformation of the upper cover of the square section of tunnel was larger than that of the circular tunnel. The shear strength of the retaining pile on both sides of the square section tunnel was considerably lower than that of the retaining pile on both sides of the circular tunnel. The anti-uplift protection measures of the designed tunnel exhibited evident protective effects on the square and circular sections. However, the protection effect for the circular tunnel was more evident compared with that of the square section. View Full-Text
