Underground research: here and there

Article Abstract:

The scale of underground construction and the technologies that make them possible have gone beyond dangerous and expensive labor-intensive operations. Advancements in design and construction methods are evident in the computers, geotextiles and specialized equipments presently being used. In this regard, a comparison of the quality, nature and quantity of research of underground construction technology efforts by the US, Japan and Europe are presented.

Life at the end of the tunnel

Article Abstract:

This article examines safety of the existing transit tunnels in terms of their ability to handle fire accidents. Research shows that efficient and multiple ventilation systems coupled with smoke extraction ducts and automated warning response systems will be helpful in handling tunnel fire outbreaks.

Light at the end of the tunnel

Article Abstract:

Engineers designed a deep tunnel 5, 900 feet long to store the polluted water during severe storms, as a part of a comprehensive program to control combined sewer overflows in Richmond, Virginia. The constructional features of the tunnel are discussed.
