Research Projects:
· Co-Principal
Investigator. “Design of stone column-improved soft ground considering
clogging effect based on long-term field study (SCF)” sponsored by Science and
Engineering Research Board (SERB),Department of Science and Technology, New
Delhi (INR 32,27,400) (2021-2024).
· Principal Investigator (India). "Landslide
Hazard Assessment in NE India along Gangtok-Tsomgo/Changu Lake and Gangtok-Chungthung-Lachen
Corridors." A Indo-Norway Joint Collaboration Project Sponsored by
MoES, New Delhi, involving Geological Survey of
Norway (NGU), Norwegian Geotechnical Institute (NGI), Wadia Institute of
Himalayan Geology (WIHG) and IIT
Kharagpur. (INR 2,11,00,000) (2017-2022).
· Principal Investigator (India) of a project
entitled “HYDRODRIL,” sponsored by European
Union, Ref. No. ID FP7-PEOPLE-2011-IRES-295225. The project is a
collaborative research between BOKU, Austria, CUG, China, Univ. of
Nottingham (UNID), UK, UNAM,
Mexico and IIT Kharagpur (India). The project is
coordinated by Prof Wei Wu of BOKU, Austria (Eu 37,400 /Eu 264,600)
(2012-2016).
· Principal
Investigator. “Experimental & Numerical Studies on Deep Excavation
under Static & Seismic Conditions” by Department of Science and
Technology, New Delhi, Ref No. SR/S3/MERC-0029/2011. The distribution
of earth pressure and corresponding response of the retaining wall system
under different combinations of cohesionless soil
with plastic fines (clay) & non plastic fines (silt) under different
construction stages is being studied with the help of laboratory model
tests and numerical modeling. The settlement profile of the ground surface
and conditions of structures near the edge of excavation is also studied
(73 Lakhs) (2012-2015).
· Co-Principal
Investigator. “Strengthening the Research and Postgraduate Teaching in the
Areas of Structural, Geotechnical, Environmental and Transportation
Engineering (FET)” by Department of Science and Technology, New Delhi,
Ref No. SR/FST/ETII-037/2008 dtd
17.03.2009 (Rs. 2.45 crores) (2009-2014).
· Principal
Investigator. “Modeling and Monitoring of Landslide Hazard in Sikkim
Himalayas (HSH)” by Department of Science and
Technology, New Delhi, Ref No. ES/11/092(50)/2003 dt. 19.03.2004. It is a part of DST’s Natural
Disaster Management Program. It includes field instrumentation and long
term monitoring of Lanta Khola landslide on
North-Sikkim Highway in Sikkim (2004-2008) (Rs. 23 Lakhs).
· Principal
Investigator of a project entitled “Theoretical & Experimental
Investigation of Strain Localization in Cohesive Soils under Plane Strain
Condition (LCS),” sponsored by Department of Science &
Technology, Govt. of India (New Delhi), Ref. No.
SR/S3/MCE/03/2001-SERC-Engg. Dt. 12-11-2002. (Rs.
13 Lakhs). The project includes development of an advanced bi-axial test
facility to study strain localization in soils. Digital image processing is
utilized to monitor shear band development with the progress of the tests
(2002-2005).
· Principal
Investigator of a project entitled “Preparation of Status Report on
Landslide Problem in Sikkim (RLP),” sponsored by
Department of Science & Technology, Govt. of India (New Delhi). Ref.
No. ES/11/092(50)/2003 dt
22-01-2003. (Rs. 30 Thousands). The project
includes visiting major landslides in Sikkim and reporting different
measures undertaken to mitigate landslide and the present status of these
slides (2003).
