ABSTRACT: Large scaled model tests were carried out to study the short-term deformation behavior of the arch-shaped tunnel which was constructed by cut-and-cover method without compaction effort for backfill material. Earth pressures acting on the tunnel lining and displacements of the lining...

... earth pressure on quay walls from backfill during shaking was observed and analyzed. A series of model shaking table tests on gravity type model quay walls with different vibration properties showed that liquefaction of the backfill soil increases the damage to quay walls. The transient behavior of...

The bending stiffness of the wall was chosen so that substantial but realistic extent of bending deformation would occur under the expected earth pressure in the model. Hence, no particular prototype was borne in mind. Many strain gauges were placed on the sheet-pile...
