Soil nailing is one of the effective methods of slope stabilization, and its stability mainly depends on the properties of both the soil and soil nails. Optimizing soil nailing parameters is an effective task to avoid installation issues. This work uses four input parameters: different shaft diameters, surcharge pressure, helical pitch, and inclination angle. The design plan for the experimentation is conducted using Box Behnken design (BBD) of response surface methodology (RSM), performed in design expert software. In addition, RSM is used to determine the optimal design combinations. A total of 25 experimental runs are taking place, and the significance of the developed quadratic model is determined using the analysis of variance (ANOVA) test. Hybrid deep belief network-based Coot optimization (DBN-CO) is also used to optimize the pull-out capacity and the safety factor during installation for more precised prediction. When compared to others the proposed hybrid DBN-CO predictive model represents the better performance with regression R = 0.99. Also least MSE & RMSE and highest R & R 2 values obtained by hybrid DBN-CO. The obtained experimental outcomes from RSM are 1.46 of safety factor, and 7.55 kN pull-out capacity. The predicted results from the proposed hybrid DBN-CO for the safety factor are 1.44 and pull-out capacity is 7.77 kN. As a result, the optimal results of DBN-CO are 3% greater than RSM, DBN, and artificial neural network (ANN). Based on prediction approaches the proposed hybrid DBN-CO results are in perfect agreement with experimental values and are additional superior to the RSM, DBN, and ANN.

The occurrence of slope instability disasters seriously endangers the safety of people’s lives and property in China. Therefore, it is essential to study the slope instability process and the interaction between soil and retaining walls. In this paper, the smoothed-particle hydrodynamics (SPH) method, based on the elastoplastic constitutive model of rock and soil, was used to simulate the entire process of slope instability and the interaction between soil and retaining walls. The model, based on the classical elastic–plastic theory, includes linear elastic deformation and plastic deformation following the non-associated flow rule under the Drucker–Prager (DP) yield criterion. By considering the plastic characteristics of geotechnical materials, this method can accurately simulate the slope movement process. The model was established, calculated, and compared with a slope example, thus verifying its feasibility. Furthermore, the motion response of the retaining wall under different conditions was studied, which provides a new numerical simulation platform for the stability checking of the retaining wall and motion analysis after the interaction between the retaining wall and slope soil.

“…Kalehsar et al [30] have presented numerical modeling using FLAC3D to study the nailed-soil slope behavior under varying surcharge pressure. A limit equilibrium and finite difference coupled approach was used by Singh et al [31] for stability analysis of nailed-soil slopes. The stability analysis of soil slope reinforced with pre-stress anchors, including an anchor parameter optimization study, was conducted by Deng et al [32] using the limit equilibrium method.…”

Finite Element Modeling of the Soil-Nailing Process in Nailed-Soil Slopes

et al. 2023

The finite element technique has been accepted as a tool for modeling geotechnical complex processes. In this study, finite element (FE) modeling of various stages of the soil-nailing process, i.e., construction stages and overburden pressure stages, is carried out considering different soil parameters, simulating with in-house developed laboratory models. The soil-nailing process built in laboratory models is idealized as a plain strain problem and modeled in PLAXIS software. The laboratory models of the soil-nailing process consist of a Perspex sheet box containing a sandy soil slope, a Perspex sheet facing, steel bars as reinforcement and a steel plate as foundation. The stress–strain relationship of the sand is represented by a Hardening-Soil model. The interface at the soil and nail is described by the Coulomb friction model. The behavior of the soil-nailing process, during the construction stage and under varying overburden pressure and varying soil density, are investigated in terms of displacements of slope and stress conditions in slope soil mass. The slope displacements and stress conditions in slope soil mass are all well presented by the FE modeling and compared with laboratory model test data. The sensitivity analysis of the laboratory models’ dimensions is carried out by three-dimensional modeling of the nailed-soil slope. It can be concluded that the developed finite element model has the potential to simulate the performance of a field nailed-soil slope during construction and working stages and could provide guidance for the construction/maintenance of soil-nailed cut slopes in granular soils/weathered rocks.
