Upper Bound Limit Analysis of Circular Tunnel in Cohesive-Frictional Soils Using the Node-Based Smoothed Finite Element Method

The Upper bound limit analysis of slope in cohesive-frictional soils using the node-based smoothed finite element method

“…The NS-FEM recently became an active research topic that has been widely applied to heat transfer analysis (Wu et al [29]), fracture analysis (Liu et al [30]), structural-acoustic analysis of shells (Wang et al [31]). Recently, Vo-Minh et al [32][33][34] applied NS-FEM for the stability of circular tunnels, dual circular, and dual square tunnels in cohesive-frictional soils. More recently, Vo-Minh [35] estimated strip footing bearing capacity factors using the node-based smoothed finite element method and second-order cone programming using the upper limit analysis.…”

Stability Analysis of Circular Tunnels in Cohesive-Frictional Soil Using the Node-Based Smoothed Finite Element Method (NS-FEM)

“…Several papers demonstrate that the NS-FEM performs well in heat transfer analysis [33,34], fracture analysis [35], acoustic problems [36,37], axisymmetric shell structures [38], static and dynamic analysis [39][40][41]. Recently, T. Vo-Minh and his co-workers [42][43][44][45] applied an upper bound limit analysis using NS-FEM and second-order cone programming (SOCP) to determine the twin circular and dual square tunnels' stability cohesive-frictional soils.…”

“…This chapter aims to summarize our research papers [42][43][44][45] using the nodebased smoothed finite element method (NS-FEM) to estimate the collapse load and failure mechanism of single and two circular tunnels in cohesive-frictional soil subjected to surcharge loading. The numerical results are available for cases with ϕ ≤ 30°, and geotechnical engineers can use them in the preliminary design stage.…”
