Title:	Versuche zum Abriebverhalten von Gesteinen bei hydraulischen Einwirkungen
Abstract:	In der Wechselwirkung von Locker- und Festgestein untereinander und mit anderen Werkstoffen bei Transport-, Lade- und Lösevorgängen ist der Abrieb als Teil der generellen Degradation ein wichtiger Parameter. Zur Untersuchung des Abriebs bei hydraulischen Einwirkungen wurden mögliche Versuche verglichen und Parameterstudien durchgeführt. Dabei wurden der Abrieb von Lockergestein aktiv als Reibladung und passiv z. B. bei Geschiebetransport betrachtet sowie wesentliche Einflussparameter ermittelt. Für die Simulation des hydraulisch induzierten Abriebs steht mit dem Micro-Deval-Versuch ein geeignetes Verfahren zur Verfügung. Investigations on the abrasion behavior of soil from hydraulic impacts To assess the interaction of soil and rock between each other and versus other materials during transport, loading and quarrying, abrasion as one part of general degradation is an important parameter. To investigate abrasion from hydraulic effects, appropriate tests are compared and parametric studies have been performed. Both, active abrasion of soil as abradant and passive abrasion e.g. due to bedload transport are considered to work out relevant influencing factors. To simulate hydraulically induced abrasion, the Micro-Deval-Test has proven its suitability.
