Numerical study on the optimum layout of soil–nailed slopes

Analysis of a Nailed Soil Slope Using Limit Equilibrium and Finite Element Methods

“…However an elastic equivalent plate element can be used as nails for slope reinforcement. As observed from the literature review [40][41][42] the bending stiffness and the axial stiffness play an important role in the simulation of the nails. If the nails are modelled using a plate element of circular cross section, then an equivalent flexural rigidity and equivalent axial stiffness has to be calculated for correct simulation of the soil nails.…”

2D Numerical Simulations of Soil Nail Walls

“…In practice, bending stiffness of the soil nails is often considered in the numerical simulations of the soil nail walls (e.g. Fan and Luo 2008). On the other hand, few researchers prefer to ignore the contribution of bending and shear capacity of soil nails in the analysis (e.g.…”

“…Mohr-Coulomb model, being the first order soil model, is most commonly used for numerical simulations in the soil nailing applications (e.g. Kim et al 1997;Smith and Su 1997;Zhang et al 1999;Sivakumar Babu et al 2002;Fan and Luo 2008). Few researchers have used advanced soil models such as Duncan-Chang hyperbolic model (e.g.…”

“…Consequently, in practice, to study the complex soil-structure interaction and to assess the performance of soil nail walls, often numerical simulations are performed using rigorous computational codes based on numerical techniques such as finite element method (e.g. Smith and Su 1997;Zhang et al 1999;Fan and Luo 2008), discrete element method (e.g. Kim et al 1997) and finite difference method (e.g.…”

Stability Analysis of Steep Nailed Slopes in Seismic Conditions: Numerical Approach

“…It has also been proved in the literature [1], that the performance of nailed soil slopes is quite excellent than the gravity retaining structures under earthquake conditions. The literature survey on the nailed soil structures reveals that lots of work has been done on the design and construction methodologies, laboratory modeling and numerical modeling of nailed slopes and excavations under static load condition [3,4,5,6,7,8,9,10]. Hong et al [1] investigated the performance of nailed soil slopes under dynamic condition in the laboratory.…”
