METHOD FOR STABILIZING A SOFT GROUND FOR A DAM OR A HEAP, AND UNIT CONSISTING OF A GROUND STABILIZED BY THIS METHOD AND OF A DAM OR A HEAP

摘要

Method for stabilizing a soft, compliant soil (1) for a dam to be built up or a heap. At the boundary of the planned embankment (4) for forming the dam or the heap, flexurally rigid walls (5, 6) driven deep into the soil (1) and consisting of sheet piles or piles are erected at two mutually opposite sides of the planned embankment, and, at the level of the surface (3) of the soft soil (1), high-strength tension members (8), in particular cables, thread bundles, chains or bands are laid parallel to one another on the soft soil (1) and are as far as possible connected inflexibly to the walls (5, 6), and a material web (7) or plastic sheet which lies on the surface (3) of the soft soil (1) and the tension members (8) and which separates the soft soil (1) from the embankment (4) is arranged between the flexurally rigid walls (5, 6). Alternatively, instead of the high-strength tension members and material web or plastic sheet, high-strength geoplastic webs (78) are connected to the walls.
