<p>This paper is dedicated to present criteria and rules for design of metro path including tunnel geometrical sections and choosing parameters, loads applied to tunnels, fundamentals of static and seismic analysis, and primaries of structural design, structural ...

<p>This paper investigates experimentally the effectiveness of a new seismic design philosophy, in which soil failure is &ldquo;utilized&rdquo; to protect the superstructure. A physical model of a simple bridge pier is used as an example. Two alternatives ...

The increments of the internal forces induced by an earthquake in the transverse section of a tunnel lining can be ascribed to the ovalisation of the section, induced by soil shear straining in the vertical plane. They can be assessed with several procedures ...

This thesis deals with the model accuracy for seismic design of immersed tunnels, like the proposed underwater artery in Thessaloniki, Greece. The soil response to seismic waves is analysed in the frequency domain by means of the domain transformation method ...

<p>Sandy soil layers may undergo compression during liquefaction. Areview of published design manuals, including the 2004AASHTO LRFD Bridge Design Specifications, indicates that some recommendations for pile design may not represent the pile response in a ...

Construction of the Canada Line Rapid Transit Project is currently underway in Vancouver, BC. The 19 km rapid transit system includes 6.6 km of cut and cover box structure – one of the longest cut and cover rapid transit tunnels in Canada. The design for the ...

An effective seismic retrofit for a sidewall of a cut and cover tunnel has not been established yet. We develop a new method of seismic retrofit for the cut and cover tunnel. We call this “polymer isolation method.” In this method, we insert a thin wall made ...

The Gujarat State Disaster Management Authority Gandhinagar and the Indian Institute of Technology Kanpur are happy to present the IITK-GSDMA Guidelines on Seismic Design of Earth Dams and Embankments to the professional engineering community in the country. ...

Existing analytical methods for the stress analysis of buried steel pipelines at crossings with active strike-slip faults depend on a number of simplifications, which limit their applicability and may even lead to non-conservative results. The analytical methodology ...

In this paper a 3-D thin shell strain analysis has been presented, regarding long cylindrical underground structures (buried pipelines and tunnels) subjected to seismic shear (S) wave excitation.
