Simple Tests for the Design Parameters and Sinkage Algorithm for Eco-bags Slope

The slope surface protective structure of eco-bags has a great difference with the conventional ones, mainly because the eco-bags slope is a flexible structure, fillers may mostly be the soils with large plastic deformation, and therefore they have some compressibility. So far, there has not been an effective algorithm for its structural sink or stability. In this paper, based on the simple onsite tests for an actual project, a practical algorithm for the sinkage amount of slope eco-bags is proposed. The algorithm and relevant calculation parameters can be obtained by simple onsite tests and the methods of soil mechanics. By results from the tests, the soils with the proposed percentage of filling materials and compaction process can be directly used in engineering practice. The calculation process of the algorithm is simple, and it has been verified by some practical projects. Thus, its accuracy is satisfactory. (C) 2012 Published by Elsevier Ltd.
