piezometer (1), which lies at the center line of the road, were almost the same from the beginning of the construction of the left half of the wall until the end of the monitoring activities. Hence, it could be concluded that after the construction of the wall, there is no hydraulic gradient through the embankment, which in turn means that there is no erosion due to seepage forces. Fig. 6: The readings of the strain gages of direction (r) of pile P54 The readings of the inclinometers embedded in the bentonite piles indicated its high flexibility because of the heave action of the pile after each construction or loading activities. The bentonite piles experienced high lateral displacement compared with the adjacent reinforced concrete pile. The monitoring system succeeded in reflecting the effect of the presence of hard and/or very soft soil deposit lenses within the soft clay layer on the developed strains and stresses. Monitoring of the reinforced concrete piles showed that they experienced small stresses compared with its ultimate capacity. The shallow embedment of the reinforced concrete pile in the lower poorly graded sand layer did not allow for any fixation or partial fixation of the pile in the sand. 1241
