Geotechnical Factors in the Dredgeability of Sediments. Report 1. GeotechnicalDescriptors for Sediments to be Dredged

摘要

Existing soil descriptor systems are not universally used, or even understood, byall groups involved in navigation dredging. As part of a 6-year study of this problem, a resource review has been conducted, which includes examination of the published literature and interviews with individuals knowledgeable in this area. The study indicates that the minimum soil identification test data necessary for the design, planning, and execution of dredging projects are as follows: (a) undisturbed soil mass properties, (b) disturbed soil material properties, (c) specific properties such as rheologic properties of a slurry, sedimentation rate in salt water, or bulking factors. Suggestions are made in the report for a standard set of descriptive terms and for a new Dredging Classification System.
