Abstract: Experimental studies on hydraulic heave with surcharge filter on the excavation side of the wall have shown that the thickness of the surcharge filter has a considerable influence on the failure-mechanism. For furthe investigation, one-dimensional flow experiments tha enable a better understanding of the influence of a surcharge filter on the failure-mechanism were conducted In these experiments, the observations were focused primarily on the influence of the surcharge filter thicknes and relative density of the sand on the critical hydraulic gradient. Furthermore the actual fracture process wa closely analyzed. This paper shows the test results of the experimental series and presents first finding.
