Investigating Stabilized Excavations Using Soil Nailing

Numerical analysis is used widely in geotechnical problems [9, 14]. Investigating the performance of excavation using field studies and numerical analyses has been reported widely in the literature [1,3,7,15]. Numerical analyses were investigated using various methods including the finite element method [12] and the finite difference method [11].
