| contents | Blast densification: A proposed methodology to quantify the amount of densification required to prevent liquefaction and flow in sandy soils Carlos Alberto Vega-Posada David Guillermo Zapata-Medina Alfonso Mariano Ramos-Cañon Ingeniería loose sands liquefaction densification soil improvement Blast densification This paper presents a methodology to quantify the amount of blast densification or number of passes required for a given project to prevent liquefaction and flow in saturated, loose sandy soils. The proposed methodology is based on the concepts of the critical state soil mechanics, and the number of passes is chosen so that the final state of stresses of the blasted layer is located below the critical state line of the soil, where a dilative response is expected. Field and laboratory results of a blast densification program conducted at a waste disposal landfill located in South Carolina, USA, are presented and used to evaluate the proposed approach. A step-by-step example is presented in detail for this purpose. This methodology could provide to engineers a rational manner to estimate how much improvement is required in the soil to meet the design objective of a particular project and the costs associated with it. 2016 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43047073007 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.80 |
