      abstract     = {The safety against seepage failure by heave must be checked
                      for an excavation pit constructed in open water or urban
                      area when a groundwater flow takes place from the upstream
                      side into the excavation pit. A seepage failure by heave
                      appears when the pore water pressure developed by
                      groundwater flow lifts the soil on the downstream side. It
                      may lead to the collapse of the excavation walls or to the
                      overall stability loss of the excavation pit.By the present
                      work, a contribution to the more exact clarification of
                      seepage failure by heave in excavation pits constructed in
                      non-cohesive soils should be given. For this purpose, the
                      problem is treated firstly in non-cohesive homogeneous
                      soils. With the help of numerical steady-state groundwater
                      flow analyses, a failure criterion is introduced for
                      three-dimensional flow conditions. Subsequently, a model box
                      is constructed utilizing the symmetry in order to
                      investigate the mechanism of the seepage failure by heave.
                      Only after thorough investigations performed in non-cohesive
                      homogeneous soils, the problem is treated in non-cohesive
                      stratified soils with the help of steady-state groundwater
                      flow analyses and model tests. Finally, the problem of
                      seepage failure by heave is investigated in both homogeneous
                      and stratified soils by means of coupled
                      flow-stress-deformation analyses.},
