GEOTECHNICAL APPLICATION TOOLS DEVELOPED

  1. LIQUEFACTION ASSESSMENT TOOL:
  2. Liquefaction is a phenomena in which when loose, cohesion less, saturated soils in undrained condition when subjected to earthquake loading or dynamic loads behave like a fluid due to subsequent loss of shear strength and increase in pore water pressure. The effect of liquefaction can be predicted in three stage: Evaluation of Susceptibility, hazard and deformations. Currently, a tool has been developed for the assessment of liquefaction hazard. Many different methods are available for the assessment of liquefaction hazard but the stress based approach has been chosen for the development of the tool.




  3. SDMWT: Tool for Seismic Design of Monopile for Offshore Wind Turbine:
  4. SDMWT is a computing tool designed as Graphical user Interface on the base of C language which serves as a computer application. This application is used for the "Seismic Design of Monopile for Offshore Wind Turbines". Considering Geo technical data along with met-ocean and Turbine data dimensions of a monopile are designed under seismic, lateral and gravity loading conditions for site specific environment. Outstanding part of the application is that it generates a 3D animated view of a monopile that gives stress distribution generated on the basis of Finite element modelling.




  5. Debris Flow Model
  6. A numerical model has been developed to predict the runout distance and flow parameters of debris flows using Finite Difference Approach. The approach is based on continuum concept with mass and momentum conservations as governing equations. The model is able to predict the shape and volume of debris flows with variation of height and velocity with respect to time and space during the flow. The model takes into account multiple rheologies, effect of land cover and different degrees of saturation.
