Abstract

Consolidation of soft sediments stored in the confined disposal facilities or mine tailing dams has challenged the scientists to come up with the best consolidation device for the past 50 years. Since the Terzaghi consolidation theory does not apply in soft sediments due to lack of permeability measurements and self-weight effect, the seepage-induced consolidation seems to be the best tool for soft sediments consolidation determination. Besides, index properties are easily obtained in any soil's laboratory and can be fast and accurate. Therefore, correlation of consolidation with index properties can help disposal facility designers to have a better perspective on the consolidation of similar sediments. This paper presents the result of seepage-induced consolidation test on six different soft soils and correlates their index properties with seepage-induced consolidation model. Finally, the correlation results are compared with the test data and similar correlations in the literature. The proposed correlation shows very satisfactory predictions to the laboratory test results.
