SUBHASH MISHRA
Dhanbad, April 13: Sanjay Kumar Shukla, a world-renowned civil and geotechnical engineering expert, said that the wraparound reinforcement technique improves stiffness in terms of the modulus of subgrade reaction.
Wraparound reinforcement technique
Shukla, a geotechnical and geoenvironmental engineering research group leader of the School of Engineering, Edith Cowan University, Perth, Australia, while delivering an expert talk at IIT ISM on the subject of ‘Wraparound Reinforcement Technique for Strengthening the Foundation Soil’, said that the wraparound can also be highly beneficial in a location of limited land width for foundation construction.
The ‘Expert Talk’ was jointly organised by the Indian Geotechnical Society (IGS) Dhanbad chapter and the Department of Civil Engineering of IIT ISM at the conference hall of the institute.
Over 100 research scholars, students and faculty members led by Prof Sarat Kumar Das, head of the Department of Civil Engineering and chairman of the Dhanbad Chapter of IGS were in attendance.

Geosynthetics and Ground Engineering
Shukla, who serves as founder editor-in-chief of the international journal Geosynthetics and Ground Engineering published by SpringerSpringer, Switzerland, said that reinforced foundation soil provides improved load-bearing capacity and reduced settlements by distributing the imposed loads over a wider area of weak subsoil.
He said, “The Wraparound reinforcement technique is based on a filled soil bag wrapped around a reinforcing geogrid forming the facing of the retaining wall.”
Shukla further said that the improved performance of geosynthetic reinforced foundation soil can be attributed to an increase in the shear strength of the foundation soil from the inclusion of geosynthetic layers.
Prof Shukla holds professorships at 10 universities, including the Indian Institute of Technology (IIT) Madras and Southern Illinois University, Carbondale, US.
American Society of Civil Engineers
He is a fellow of the American Society of Civil Engineers and Engineers Australia and a life fellow of the Institution of Engineers (India) and the Indian Geotechnical Society.
