Abstract
This project explores the uses, values and limitations of closed form solutions in specific areas of geotechnical engineering. Three closed form (analytical) solutions, Kelvin's, Boussinesq's and Mindlin's solutions have been chosen and researched to determine their applications in geotechnical engineering. These applications have been examined with the aim to modify, further define and/or extend upon them so that they may be applicable to new problems.
A review of research on Kelvin's, Mindlin's and Boussinesq's solutions gave an indication of the ways each of the solutions could be applied to solve for certain problems. After noting the likeness of the solutions and the accomplishments that had been achieved with the relatively popular Boussinesq's solution, the aim was to subject the lesser known and utilised Mindlin's solution to similar concepts.
The integration of Mindlin's solution for a sub-surface circular loading was performed and is shown here in full, something which does not appear to have been published. From this Newmark inspired Mindlin based influence charts were generated which were found to be of little practical use. Following this the relationship between both Boussinesq's and Mindlin's solutions was investigated and analysed resulting in the production of a design chart that may be applicable to a bi-loaded anchor system.
On a whole the work undertaken in this dissertation showed the main values of the closed form solution in the area of stresses in soil masses were that of insight and flexibility, and their main limitation was that of the simplifying assumptions that were required to be made.
