Sustainable Approach to Underground Metro Rail Structures for Longer Service Life
Owing to the surge in urban population, cities in developing countries need sustainable transport system such as underground metro rail with a longer service life. This paper discusses the various sustainable means involved during planning, design and construction of these underground metro rail structures for achieving a longer service life. The transport planning would include choosing the alignment, future ridership etc. Sustainable design approach includes stringent limitations on crack width and deflection, adopting minimum cement content, suitable concrete grade, appropriate fire rating, minimum cover and other specifications in line with the environment the structure is exposed to. During construction, sustainability shall be ensured through systematic construction methods and material testing, monitoring through proper geotechnical instrumentation and non-destructive tests such as sonic logging, inclinometers and crack meter tests. Post construction, the built structure shall be checked for any defects such as grout loss, honeycombing, dry and wet cracks and suitably rectified.
