Methods of lateral stability analysis of well
Short answer
Methods are Terzaghi's simplified analysis (light and heavy wells), IRC:45 method (modified Terzaghi), Banerjee and Gupta's elastic/subgrade reaction approach, subgrade reaction (Winkler) method, and finite element methods for complex cases.
Name the different methods to analyze the lateral stability of a well foundation.
The lateral stability of a well foundation (resistance to horizontal force and moment) is analysed by:
- Terzaghi's analysis (simplified), for light and heavy wells.
- IRC:45 method (the Indian Roads Congress code, based on the modified Terzaghi method).
- Banerjee and Gupta's method (the elastic / subgrade-reaction approach).
- Subgrade reaction (Winkler) method.
- Finite element methods for complex cases.
