In many densely populated cities, buried networks of urban services, such as facilities and
sewage tunnels or sewer pipes are constructed adjacent to or beneath nearby building …

In recent years, the vulnerability and protection of subsurface structures under blast loads
became a fundamental issue in terms of security (loss of lives and structural damage). A …

In some subsurface urban development projects, bedrock faults intersecting with the tunnel
path are inevitable. Due to the high costs of urban tunnel projects, it is necessary to study the …

Pseudo-static analyses are performed to investigate the seismic response of circular tunnel
considering the induced stress relief in the surrounding soil due to excavation. A set of two …

Methods: For this purpose, Tehran Metro Line 6 was simulated numerically to investigate the
effects of different parameters on the surface settlement, and 85 datasets were prepared …

Modern rapid urbanization and the density of structures present a unique challenge for
construction on slopes. An effective means of overcoming this issue is to build tunnels and …

The seismic response of a fabricated subway station is a complex structural connection
problem that depends on the mechanical properties of the joints. In order to obtain the …

The seismic response of buried oil and gas pipelines is mainly influenced by the site soil. In
this paper, a bidirectional laminar shear continuum model box is developed for the site …

Based on the theory of complex function, the seismic response of tunnel structure in
inhomogeneous elastic right-angle space under different stiffness is solved. The …

The study of seismic behavior of underground tunnels is of particular importance due to the
fact that they are completely enclosed in the soil or rocks and also these structures have a …
