Numerical modelling of full-scale tests on drystone masonry retaining walls

摘要

The behaviour of four drystone masonry retaining walls of different geometry has been modelled numerically using the discrete element code UDEC, and the results have been compared with the field trials carried out by Burgoyne in Ireland in 1834. By using appropriate soil and wall mass Densities, strengths and stiffnesses, it was possible to repro- Duce in the numerical analyses the field behaviour observed By Burgoyne. Reasonably close agreement was obtained be- Tween the horizontal components of earth pressures calcu- Lated in the numerical analyses and using the earth pressure Coefficients given by Caquot and Kerisel.
