Abstract

This study investigates the impact of barrette wall thickness on the stability of the deep excavation project, particularly focusing on horizontal and vertical displacements, axial forces, and moments. Using the finite element method (FEM), simulations were conducted on barrette walls with thicknesses of 600 mm, 800 mm, and 1000 mm. The results revealed that while thicker walls marginally reduce both horizontal and vertical displacements, the improvements are not significant enough to warrant the additional costs. Statistical analysis, including ANOVA and the Games-Howell test, confirmed barrette wall thickness on structural stability, with the 600 mm wall demonstrating sufficient strength to maintain the integrity of the excavation. This suggests that a 600 mm wall thickness provides the most cost-effective solution for urban excavation projects without compromising safety. The findings contribute to the existing body of knowledge by offering practical insights into optimizing wall thickness for deep excavation, emphasizing the importance of balancing structural performance with economic considerations.
