Behavior of a new laterally top-loaded post-grouted micropile in highly porous lateritic soil

The use of micropiles has been increasing in recent years, mostly for horizontally loaded cases. Given the little information about this foundation type under lateral top-loading, especially high-porosity and collapsible soils, a total four transversal loading tests were carried out new post-grouted micropile configuration with length 17 m diameter 0.3 m, two natural soil moisture conditions flooded conditions. Load-displacement curves horizontal reaction coefficient obtained. Results compared other pile types laterally tested same geological geotechnical contexts. Generally, results better than types, mainly saturated condition. proved to be more efficient alternative local lateritic treatment when soil-cement treatment.
