Industrial Research and Development

Various geotechnical consultancies including Geotechnical investigations, failure case studies, slope stability analyses, foundation design, ground improvement techniques, Design of reinforced earth structures, earth and earth retaining structures, design of shallow and deep foundations for many major bridges and other structures, dynamic stability of the backfills, dynamic testing and analysis of foundations for many important structures, shear wave velocity profiling, design of earth dams and tailing ponds, soil nailing, rock slope stability using grouted nails, etc. have been handled.

As a Geotechnical consultant, advised and acted as consultant covering a wide range of civil and geotechnical structures.

  • Geotechnical Consultant: Slope stability and foundation design for one of the world's highest bridges (owner: Northern Railway, Govt of India, Implementing agency: Konkan Railway Corporation Limited, Govt of India) in Jammu and Kashmir for M/S AFCONS (Chenab Bridge) and GAMMONS (Anji Khad Bridge).
  • Earth dam designs for both raw water ponds and tailing ponds (both for red mud and ash) for many agencies which involves review of geotechnical reports, design of dykes including complete technical specifications and providing tender drawings, etc., Interacted with engineers of NALCO @Angul and Damanjodi, OPGC, KPCL, Hindustan Zinc Limited @Rampur Agucha mines (mine tailings), Vedanta Alumina Limited @Lanjigarh (Red mud and fly ash), Hindustan Zinc Limited @ Rajpur Dariba Mines (mine tailings), Hindustan Copper Ltd(mine tailings), JSW (raw water reservoir), ESSAR, etc.
  • Dynamic testing and analysis of foundations for Human Centrifuge at Indian Aerospace medicine at Bangalore, 3 axis motion similar at ADE, Bangalore, Moon Tracking 32m and 18m dia antenna foundations for ISTRAC and ISRO (Dept of Space), 32m dia antenna at Nazafgarh, New Delhi. Dynamic stability of compacted sand fill in the Nuclear Island, PFBR project for IGCAR, Kalpakkam, India: Carried out detailed analysis of liquefaction studies both using laboratory tests and field tests and recommended measures for mitigating liquefaction and dynamic response of foundations of retaining walls, RE walls, tunnels and trenches on the sandy backfill. Presented the findings to Atomic Energy Regulatory Board (AERB), Mumbai; BHAVINI, and IGCAR Engineers, Kalpakkam.
  • Irrigation works: Krishna Bhagya JalaNigam Limited (Karnataka Govt.): Investigations on the stability issues and failures of canal slopes of NLBC in UKP
  • National Aluminium Company (NALCO), Damanjodi and Angul: Failure investigations of ash dyke, Inspection and monitoring of ash pond and red mud pond dykes, safety issues in dam maintenance, and design of further raising of earthen and ash bunds. Works include site inspections during construction, quality control issues, etc. Several failures of ash dykes were investigated and remedial measures were also suggested.
  • For NMDC major works involving soil-nailing techniques, reinforced earth walls and slope stability analysis for structures of Bailadilla iron ore deposits Nos 10, 11, and the new one 11B. Instead of conventional concrete structure it was suggested to go for soil nailed / reinforced earth retaining walls.
  • For MECON major work involved is in the ground improvement technique for storage of iron ore heaps on soft marine deposits which extends upto 15 meters using geocells and also designed several pile foundations for structures.
  • For RITES, Vetting the design of highest reinforced earth railway embankment in Jammu & Kashmir, 70m tall. Vetting of reinforced earth structures for many agencies such Ms/ Venktapathy Raju constructions, AFCONS Infrastructure, Feedback ventures, etc. Vetting of Arch span bridges for Reinforced Earth company, ATES- Soil reinforcement division, etc.
