UPLIFT OF TUNNELS AND PIPES IN SOFT CLAY

The paper examines the potential for uplift on shallow tunnels and large diameter pipes in soft clay. Methods of evaluating the uplift force and resistance to uplift are presented using both a simplified approach and a computerised numerical model. The formulae for the simplified approach are derived and the large strain, finite-difference numerical model is described. Results of both simplified and computer approaches are compared and the paper concludes with a discussion on the limitations of the assumptions and methods of analysis. (Author/TRRL)
