“…Optimum installation angles based on failure planes can be calculated, and applications and software packages are available to determine critical nail positioning and depths to ensure soil stability (Ismail et al 2018, Chen andLiu 2007). Various parameters such as grouting pressure, overburden pressure, soil dilation, degree of saturation, and roughness of the nail surface can all have an effect on the pullout capacity of the nail, a common critical parameter for design (Sharma et al 2019a). Some studies indicate that the force used to drive the nail can be optimized to provide a shock wave to deform the soil and provide a bond to the nails (Smith et al 2009).…”

Soil erosion of cover for earth covered magazine (ECM) storage presents a unique challenge to traditional embankment practices. Due to the strict guidelines on the necessary soil cover, as well as material allowed for use in erosion deterrence, many traditional soil erosion techniques are not allowable. This report investigates current soil erosion techniques and their applicability to magazine cover focusing on regulations, costs, and ease of implementation. The techniques investigated were based on currently used techniques from 2003 to the present but did not include researchonly stage mechanisms. The objective of this research effort was to investigate currently available erosion mitigation methods and their feasibility for ECM application. Main areas of concern for ECMs are envisioned to be cost, ease of implementation, and potential for added debris. Based on the reviewed literature, it appears that chemical or vegetative stabilization are likely the best methods for ECMs' erosion prevention. This assumes that simple soil compaction is not adequate, as it is otherwise generally the best approach. After a selection is made of a proposed solution to this issue, additional testing is suggested as a proof of erosion deterrence.

“…Traditional methods may struggle to handle complex loadings or dynamic forces that can influence slope stability, such as seismic or cyclic loading. Sharma et al [15] employed the FEM to examine the stability of steep slopes reinforced with soil. Also, the impact of altering soil parameters, precisely the impact of cohesion and angle of internal friction on embankments with steep slopes was investigated with varying heights (6m-30m).…”

In geotechnical engineering, the stability analysis of reinforced soil slopes is important to ensure the safety and longevity of infrastructures. In this study, a novel multi-objective particle swarm optimized RF-SVR (random forest and support vector regression) model aimed to evaluate the stability of reinforced soil slopes. The proposed Hybrid RF-SVR-MOPSOA model combines the advantages of both machine learning techniques and optimization algorithms and offers enhanced predictive accuracy and efficiency. Assessing the model's effectiveness involves proposed model was compared with three traditional regression models: Elastic net regression (ENR), ridge regression (RR), and lasso regression (LR). Various performance assessment parameters and ROC curve plots were employed to determine the most suitable model for reinforced soil slope stability analysis. The findings indicate that the proposed hybrid RF-SVR-MOPSOA model demonstrates superior performance compared to other traditional regression models. This innovative approach significantly expands the possibilities for enhancing the assessment of slope stability and ensuring safer and more resilient infrastructural development.

“…Although this approach is computationally more expensive, it can provide detailed information about the status of the slope [11,12]. The effects of soil parameters (angle of internal friction and cohesion) [13], soil suction and ground water table [14] on the stability of soil slope have been previously investigated. Some studies analyzed the influence of spatial variability, such as heterogeneity and discontinuity within the granular assembly, on the failure behavior [15,16].…”

Integrated numerical study of rainfall-induced landslides, from initiation to propagation using saturation-based rheological model

This paper presents an integrated two-dimensional numerical framework for simulating rainfall-induced landslides from instability initiation to post-failure flow. To describe the entire 2 process, three steps are considered in this study: 1) a coupled hydro-stability analysis which detects the failure plane using the Finite Element Method (FEM) (pre-failure stage), 2) computing the local rheology of the failed mass (wet sandy soil) based on the water saturation at the onset of failure, using the saturation-based rheological model (transition stage), and 3) a continuum-based propagation analysis which solves the flow of the wet material by employing the Smoothed Particle Hydrodynamics (SPH) method (post-failure stage). Finally, to investigate the influence of rheological model on the post-failure behavior, the computed final deposition profile and flow kinetic energy are compared with those of a viscoplastic model.
