The safety of underground energy transmission pipeline network is threatened by traffic,
earthquakes, explosions, and other stresses. To solve the problem of damage to the …

The problem considered in this paper is for the stability evaluation of a rectangular tunnel in
undrained clay during lining process. The approach adopted involved the use of …

This study evaluates the stability of rectangular tunnels in cohesive-frictional soils under
surcharge loading using a combination of IsoGeometric Analysis and artificial neural …

The segment joints of a shield tunnel are generally the weak components of the structure,
and they can be considerably damaged under strong seismic loading, thus influencing the …

This paper presents a mixed formulation based on the node-based smoothed finite-element
method for estimating seismic slope stability. The final form of Hellinger–Reissner is cast as …

This paper presents a stable node-based smoothed finite element method (SNS-FEM)
based on the upper theorem for stability analysis of a square tunnel in cohesive-frictional …

The stability of a wide rectangular tunnel in spatially variable soils is investigated using deep-
learning surrogate models combined with a mixed formulation of limit analysis. The mixed …

This paper introduces a new formulation of limit analysis based on nodal integrations for
calculating static and seismic collapse loads in geotechnical engineering. Unlike the …

The Shengli tunnel sustained significant damage during the 2022 Luding earthquake (Mw
6.6), with numerous circumferential and inclined cracks observed in the tunnel lining. This …

This paper presents a stable node-based smoothed finite element method (SNS-FEM)
