Great East Japan Earthquake, JR East Mitigation Successes, and Lessons for California High-Speed Rail, MTI Report 12-37 [PDF]

open access: yes, 2015
California and Japan both experience frequent seismic activity, which is often damaging to infrastructure. Seismologists have developed systems for detecting and analyzing earthquakes in real-time.

High speed/high capacity railway and regional development - evaluation of effects on spatial accessibility [PDF]

open access: yes
In the last decade the theme of high speed infrastructure in Italy has been deeply debated, with different political and technical opinions, which have expanded the time for projects and constructions. As a consequence of this long debate, a redefinition

Lateral Shear Stress Calculation Model Based on Flow Velocity Field Distribution from Experimental Debris Flows

open access: yesInternational Journal of Disaster Risk Science
Debris flows continuously erode the channel downward and sideways during formation and development, which changes channel topography, enlarges debris flow extent, and increases the potential for downstream damage.

Collaborative stress of concrete-filled steel tube tied-arch beam-column support based on the double-layer elastic foundation beam theory

open access: yesFrontiers in Built Environment
The construction of concrete-filled steel tube tied-arch bridges typically employs the “beam first and arch later” methodology. In this approach, tie beams are initially constructed on temporary supports, followed by the erection of the arch ribs.

High-speed railway lines

open access: yes, 2014
Japan was the first country that built railway lines for high speed travel. Because of the mountainous terrain, the existing network consisted of 1,067 mm (3 ft 6 in) narrow gauge lines, which took indirect routes and could not be adapted to higher speeds. Consequently, Japan had a greater need for new high speed lines than countries where the existing
