Abstract

This study compares the performance of diaphragm wall and secant pile as excavation support systems in a 12-meter-deep excavation project at Oakwood Slipi Hotel. The analysis was carried out using the finite element method with PLAXIS 2D software, focusing on key parameters including safety factor, lateral deformation, wall deflection, internal forces, and carbon emissions. The results show that the diaphragm wall achieved a slightly higher safety factor (1.851) compared to the secant pile (1.776), with smaller lateral deformation of 64,53 mm compared to 80,33 mm for the secant pile. In terms of deflection, the diaphragm wall recorded 61.01 mm (0.508%H), slightly above the permissible limit, while the secant pile reached 75.7 mm (0.63%H), exceeding the allowable standard. From an environmental perspective, the diaphragm wall produced 37.088 tons of CO₂ emissions per panel (98.64 m³ of concrete), which is approximately 29.5% lower than the secant pile at 52.622 tons of CO₂ (139.953 m³ of concrete). Overall, the diaphragm wall demonstrated superior performance in controlling deformation, resisting internal forces, and reducing carbon emissions, leading to the conclusion that diaphragm wall is the more appropriate and sustainable choice compared to secant pile for deep excavation projects.
