Certain errors in experimental determination of earth pressure on models of retaining walls
- 52 Downloads
In investigations of model retaining walls of different design, to obtain reliable results the following observations are necessary: the horizontal stress state of the backfill and foundation, conformity of the conditions of support of the model and full-scale structure, conformity of the flexural rigidity of the walls, and identical conditions of construction with full-scale walls.
It is mandatory to measure the displacements and deformations of the model retaining walls.
The earth pressure on retaining walls should be measured by sensors having the necessary rigidity. A rigidity close to the deformative characteristics of the wall material is desirable.
In investigations of retaining walls one should use mutually controlling measurements, i.e., the earth pressure should be determined with respect to the diagram measured by sensors and with respect to the support forces; the bending moments should be checked by simultaneously measured deformations, etc.
