<p>In order to study the effects of a seismically induced tunnel&ndash; ground interaction, two-dimensional numerical analyses are performed using the sofware ANSYS. The study employs a coupled beam&ndash;spring model subjected to earthquake loading that is ...

<p>Ever increasing population of large cities, density of transportation, and need for storage capacity have led, inevitably, to an increased use of underground facilities. Tunnels in urban environment are often located at small depths underneath densely populated ...

<p>Increasing demand on infrastructures increases attention to shallow soft ground tunneling methods in urbanized areas. Especially in metro tunnel excavations, due to their large diameters, it is important to control the surface settlements observed before ...

<p>The expansion of urban populations comes with an associated demand for increased public transport. An often utilised solution is to construct a rapid transit system within tunnels. Generally, a pair of tunnels are constructed within relative close proximity. ...

<p>In this paper, ground movement in a highly populated region of Iran&rsquo;s capital city, Tehran, induced by excavation and construction of 7 the line of Tehran subway has been investigated. It was aimed to analyse the ground displacements and surface settlement ...

<p>The utilization of underground space becomes a more important issue in megacities of the world in order to build more functional and advanced cities. However, because a lot of underground structures such as lifelines have already been developed in the megacities, ...

The tunnel of the Tabriz urban railway line 2 (TURL2), Iran, will pass through an underground commercial center on its way. Too little distance between the tunnel crown and the underground structure foundation will probably cause collapse or excessive settlement ...

<p>This paper presents the results of an investigation on the characteristics of tunnelling-induced ground settlement in groundwater drawdown environment. The dynamics of the effect of groundwater drawdown on the ground settlements are first investigated using ...

<p>The tunnel of Bois de Peu is part of a project of the south-eastern Besan&ccedil;on (France) by-pass. An exploration gallery permitted to highlight the presence of eighteen geological units and to distinguish four sorts of materials: limestone, marls, clays ...

<p>A new method &ndash; fuzzy system combination neural network was used to estimate ground surface settlements. According to the measured data of Shanghai No.2 Subway, and considering various kinds of factors synthetically, an ANFIS fuzzy neural network prediction ...
