DEFORMATION OF EARTH RETAINING WALL DUE TO THE INHIBITORY EFFECT OF
COMPOSITE WALL AT THE TIME OF REMOVAL OF THE GROUND ANCHORAGES
F.Nakazawa, K.Numakami, and K.Shibazaki
In the near the railway underground work, we measured deformation of the earth retaining wall and strain of the legs of the composite wall in the process of multi-stage removal of the ground anchorages. As a result, it was confirmed that the bending strain of the legs of the composite wall by the drying shrinkage of upper slab occurs. In addition, depending on the shape increase of deformation of the earth retaining wall in the process of multi-stage removal of the ground anchorages, than during the removal of the composite wall just above ground anchorages, we confirmed that at the time of removal of the upper ground anchorages, a large bending moment of the composite wall occurs.
