R | Nashed, R | Shenthan, T | Kanagalingam, T | Ecemis, NEditor: New York: University at Buffalo, 2006Descripción: 101 pISBN: ISSN 1520295XTema(s): INGENIERIA SISMICA | COLUMNAS DE PIEDRA | VIBRACION -- -MEDICIONESClasificación CDD: 624.1762 Recomendación de contenido: The objective of this report is to introduce a rational analysis procedure and design guidelines for liquefaction hazards mitigation in saturated sands and non-plastic silty sands using Dynamic Compaction (DC) and Vibro-Stone Columns (SC). A numerical model was developed to simulate the densification processes during both techniques through quantifying pore pressure generation due to vibrations caused by successive impacts on the ground surface or repeated insertions of a vibratory probe into the ground. The effects of site-specific conditions such as hydraulic conductivity, fines content, etc., were quantified for a range of energy contents delivered to the soil at a specific spacing. Based on the results, design charts and design guidelines for liquefaction mitigation in silty soils using DC and SC are provided. Design procedures and design examples are also included.
