Abstract

Due to the continuous development of urban areas, excavation has become a crucial part of the building’s construction. From the geotechnical point of view, excavation safety must be considered. Nail walls are an economical solution, widely used to support excavations. In this study, the construction of a nailed wall is simulated using a limit equilibrium method (LEM) to study the excavation stages effect on the factor of safety (FS). The variability of the soil properties and nails’ bonding strength are considered to capture the nailed wall reliability index (RI). The Janbu corrected method coupled with the Latin Hyper Cube is used to estimate the FS and RI. The impacts of the correlation length between the soil parameters are investigated on the RI.
