My research interests include Pile
foundation, Soil Arching, Reinforced Earth Structures and Liquefaction
Potential evaluation. Being an engineer and a researcher, I think, it is
important to solve existing problems applying innovative while evaluating the
practical applicability and feasibility of the proposed solution.

Both laboratory model and cast in-situ
pile load tests have been carried out to study the effect of compressive load
on uplift capacity of piles and pile groups. Scaled Model reinforced concrete
footings (1:3) have been fabricated to study the depth of embedment on pull out
capacity. The footings have been instrumented to understand the load transfer behavior. The study focuses on nonlinear stress-strain behavior of soil and load-deformation
behavior of piles and footings under uplift and compressive loads.
In India, the cities and towns in Indo-Gangetic plains
are within a distance of 300 km from the identified seismic gaps in the great
Himalayan ruptures which has high potential for future earthquakes. With large
overburden of alluvial deposits in these areas, it becomes necessary to study
the liquefaction. It includes development of a model for dynamic deformation
characteristics of soils from north India considering soil strain.
The increase in construction material and the scarcity
of raw material initiated the researchers and planners working to find waste
material or substitute material which are environmentally friendly and
economically sustainable. The static and dynamic properties of stabilized soil
by using waste materials and its application to problems like road pavement and
railway embankment have attracted wide attention throughout the world by
researchers.
Fiber Reinforced Polymer is a composite material
consisting primarily of two materials, fibers and a resin matrix. FRP has the
advantages such as (i) High resistance to fatigue and
corrosion degradation, (ii)High strength or stiffness to weight ratio. Weight
savings are significant ranging from 25- 45% of the weight of conventional
metallic designs. Fiber
composites have been a viable option in replacing traditional pile and footing
materials such as concrete, steel and timber in harsh environmental conditions
such as exposure to water, chemicals etc.
Development
of Models and Design Methodology for Railway Formation with and without Geosynthetics (eg. Geogrid/ Geocell) for axle load for 25 ton and
32.5t (up to speed of 100 kmph) and for passenger trains up to speed of
160 kmph will make better performance of track with increased standard of
safety and reduced construction as well as maintenance cost. It also reduces
the requirement of land excavation and hence will have positive impact on the
environment.
