Seismicity : Assessing Response Characteristics of various soils against Liquefaction and as well as in the areas of Soil Structural Interactions

Hello..first of all congratulate you for thinking to select the socio economic relevant Ph.D topic. Kerala has faced serious threat on landslide in the recent past and so topic on landslide would be useful for you.

The important issue on today due to urbanization, the extension of infrastructure development in horizontal is difficult so only vertical is possible..think of new kind of foundation supporting system for high rise building.

Another very important activities in a typical urban environment such as ground movements due to various man made activities like deep excavation for new construction, metro tunnel, embankment or earthquake..the stability of an existing structures closer to these activities are questionable and need research for safeguarding the existing structure due to urbanization..

Geoenvironmental point of view the main issue on today is how to dispose the corona based various medical relevant waste?..mostly they are trying to dispose on the ground by simply dumping into the ground. There are serious concerns on contamination of the ground due to disposing corona based tools in ground.

The waste materials as produced from many industries are disposing on or into the ground..when these waste are interacting with water and the ground, the ground gets contaminated and need proper guideline design for safe disposal of all industries based waste..you can think many topics like this but need to select on one such social relevant topic and collect literature on the chosen field..you are most welcome for any support on your study..ok all the best in your research..

Effect of intesive vegetation on the stability of protective structures. In practice, it is often the case that protective structures (such as dikes or dams) are gradually overgrown not only extensively but intensively by vegetation, such as trees, shrubs, etc. The effect of intesive vegetation on the structural stability of protective structures is not clear. As a result of the generally conservative attitude of engineers, especially in the face of uncertainties, vegetation is therefore prohibited on such structures. A study that systematically analyses such effects and derives a theory as to whether, and if so at what point, intensive greening can be permitted, has the potential to have a wide impact in environmental terms, but also operationally.

Good day, Shimol Philip

I think the recent Sustainable and Green Approaches in Geotechnical are as follows : -

- Study the performance of Helical Group pile (as more sustainable than other piles) in collapsible soil ( or under siesmic loading , Helical pile supported machine foundation , ...)

- Comparison study between Helical pile and driven pile in varios soil type (experimnetal , numerical , FEM )

- Improvement of varios type of soil by adding a sustainabale material such as ( Microbial Biopolymers like Gellan ,Ager, Xanthan , else ..)in Soil Treatment for Future Environmentally-Friendly
