摘要

A series of trap door tests was conducted to evaluate the increment of earth pressures acting on a buried structure in a high embankment due to differential settlements. A model box was placed on the centre of a soil chamber having movable base platens at both sides.Differential settlements were given by moving the base platens down simultaneously.Effects of box depth, construction/settlement history, and mechanical properties of backfill soil on the change in vertical earth pressure at the top of the box are mainly presented. A simple calculation for the increment of vertical earth pressures is also shown.
