Abstract
Assessing liquefaction potential, in situ screening, and remediation of non-plastic silty soils are difficult problems. Presence of silt particles among the sand grains in silty soils affects the soil response in each of the above cases in different ways. First part of this paper addresses the effects of silt content on liquefaction resistance, hydraulic conductivity, and coefficient of consolidation of silty soils compared to clean sand. Secondly it addresses the effects of silt content and consolidation characteristics on cone resistance of silty soils and sand. A relationship between normalized cone resistance, liquefaction resistance, and consolidation characteristics is presented. The third part of the paper focuses on the effects of silt content and soil permeability on the effectiveness of dynamic compaction (DC) and vibratory stone column (SC) supplemented with wick drains to densify silty soils and mitigate liquefaction..
