Static and dynamic behaviour of model wall with reinforcement

A series of eight model tests was carried out using a rigid rotating wall with and without reinforcing strips. The reinforcement was strong enough not to rupture during all phases of the experiments. The resultant overturning moment due to earth pressure and the forces in the reinforcing strips at the face of the wall were measured as the wall was rotated outwards. The walls with attached reinforcing strips which were still self supporting after a static test to the point of failure in the backfill, were then subjected to horizontal shaking and the outward movement recorded as a function of time and magnitude of acceleration. With increasing acceleration the outward rotation would quicken with overturning failure imminent. This critical acceleration showed a similar relation to the length of the reinforcing strips as the factor of safety against overturning as evaluated from the static tests: both increased almost linearly with reinforcement length, at least up to a length/ height ratio of 0.8.
