Given the little information about this foundation type under lateral top-loading, especially in high-porosity and collapsible soils, a total of four transversal loading tests were carried out in a new post-grouted micropile configuration with length of 17 m and diameter of 0.3 m, two in natural soil moisture conditions and two in flooded conditions. Load-displacement curves and the horizontal reaction coefficient of the new micropile were obtained. Results were compared with other pile types laterally tested under the same conditions and in the same geological and geotechnical contexts. Generally, results were better than the other pile types, mainly under saturated condition. The new micropile proved to be a better and more efficient alternative for local lateritic soil treatment when compared with the soil-cement treatment. 2023 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49677978015 https://www.redalyc.org/journal/496/49677978015/ https://www.redalyc.org/journal/496/49677978015/html/ https://www.redalyc.org/journal/496/49677978015/49677978015.epub https://www.redalyc.org/journal/496/49677978015/movil https://doi.org/10.15446/dyna.v90n225.104807 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.225 Vol.90 |
