Researchers at the Indian Institute of Technology (IIT) Mandi and Durham University in the United Kingdom, have developed suction monitoring setup for soil cyclic triaxial testing to investigate the impact of climate change on railway embankments. The study was conducted by Dr Ashutosh Kumar, Assistant Professor, School of Engineering, IIT Mandi, and co-authored by Dr Arash Azizi, Assistant Professor, University of Portsmouth, UK and Professor David Geoffrey Toll, Department of Engineering, Durham University, UK, IIT Mandi said in an official statement.
The main component of railway infrastructure is the trackbed, which is supported by earthworks. This is mainly used to support the track infrastructure and carry the load imparted by the moving traffic. The present design protocols only consider the load developed due to the moving train thereby ignoring the real case scenario of changing the natural state of the soil due to ingress and egress of water.
