A Combined Slump-Sliding Test for Dredged Fine Sediments

CODEN: GTJODJ

Abstract

This study presents a new laboratory apparatus for measuring and estimating the ability of shoveling, loading, and transport of fine soils and sediments. This device permits the investigation of the slump and sliding behavior of fine sediments based on their consistency and water content. Initially, a manual version of the apparatus was designed. The combined slump-sliding test (SST) and its use through a simple procedure were described in detail. Measurements done during tests on three different sediments and smooth steel support allow the presentation of the typical results obtained from the SST test. Because consistency governs the slump and sliding behavior of sediments, grain size distribution and Atterberg limits are the most useful characteristics of sediments. Typical relationships among slumps, cone footprints, and sliding rotation angle versus water content during moistening of sediments were established and explained. Based on these relationships, criteria for the ability to shovel sediments were proposed.
