Predicting 2D ground movements around tunnels in undrained clay (2006)
Journal Article
Osman, A., Bolton, M., & Mair, R. (2006). Predicting 2D ground movements around tunnels in undrained clay. Géotechnique, 56(9), 597-604. https://doi.org/10.1680/geot.2006.56.9.597

A new analytical method is introduced for calculating displacements due to tunnelling. This is conceived within the framework of the bound theorems of plasticity, but allowing for soil strain-hardening. The ground displacements due to tunnelling are...

On the kinematics of 2D tunnel collapse in undrained clay (2006)
Journal Article
Osman, A., Mair, R., & Bolton, M. (2006). On the kinematics of 2D tunnel collapse in undrained clay. Géotechnique, 56(9), 585-595. https://doi.org/10.1680/geot.2006.56.9.585

A kinematic plastic solution has been developed for ground movements around a shallow, unlined tunnel embedded within an undrained clay layer. In this solution, the pattern of deformation around the tunnel is idealised by a simple plastic deformation... Read More about On the kinematics of 2D tunnel collapse in undrained clay.

Ground movement predictions for braced excavations in undrained clay (2006)
Journal Article
Osman, A., & Bolton, M. (2006). Ground movement predictions for braced excavations in undrained clay. Journal of Geotechnical and Geoenvironmental Engineering, 132(4), 465-477. https://doi.org/10.1061/%28asce%291090-0241%282006%29132%3A4%28465%29

The writers introduce a design approach for braced excavations based directly on the data of carefully chosen soil tests, conceived within the framework of plasticity theory, but allowing for strain hardening. Mobilized shear stresses beneath and aro... Read More about Ground movement predictions for braced excavations in undrained clay.
