Abstract
On the most important wall of our diagnosis, a synthesis of the tension results is compared to a theorical approach. A particular focus is done on the elements located at the foot of the wall and interfering with the tension results.

One of our diagnostics was performed on 590 tie rods positioned on 12 lines. The analysis of the force values for each line of tie rods shows a distribution of the thrust forces in accordance with the theory (Fig. 8.1).
For each line of tie rods, the force histogram was made with the calculation of the average force value per line.
A calculation of the thrust forces was carried out with the following assumptions.
C = 1.5 t/m2 cohesion.
Phi = 25°—angle of internal friction.
and is compared to the results of the dynamic stiffness calculation (Fig. 8.4).
The force values calculated on the last three tie rows are influenced by the presence at the foot of the wall of a concrete structure that collects and evacuates runoff water (Fig. 8.5).
The preceding observations draw attention to the representativeness of the tests on the anchors. The tests carried out mainly at the foot of the wall for reasons of ease of access constitute a particular approach which in general is not representative of common cases.
