Local soil conditions can significantly modify the seismic motion expected on the soil
surface. In most cases, the indications concerning the influence of the underlying soil …

Transport infrastructure, such as tunnels and underground structures, are usually built using
reinforced concrete solutions. Since the 1970s, many transport structures (culverts, bridges …

The crucial role that underground structures play today in transportation and utility networks
makes their seismic vulnerability a fundamental topic. The present paper deals with the role …

Underground structures are vulnerable to strong earthquakes, with their central columns
being prone to damage owing to their insufficient resistance capacity. In this study, an …

Underground structures must be able to support both static overburden and seismic loads.
Previous work has found that the dynamic amplification of stress waves impinging on a …

This paper presents the effect of horizontal and vertical earthquake force on the stability of a
single circular tunnel in cohesive-frictional soils using a stable node-based smoothed finite …

The growing use of underground structures, specifically to facilitate urban transportation,
highlights the need to scrutinize the effects of such spaces on the seismic ground response …

This research proposes the analytical formulations for the vertically aligned twin tunnels
under the sinusoidal form of seismic excitation in the case of the damped free vibration. The …

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 …

With the acceleration of urbanization, the distance between the underground structure and
the aboveground structure is becoming smaller and smaller, and the mutual influence …
