Micropilotes raíz para reforzar cimentaciones de viviendas construidas sobre suelos vulnerables a licuefacción sísmica.

Abstract

This research was developed with the purpose of providing a socio-environmental and innovative solution to a common and recurrent engineering problem in countries with seismic and geological characteristics similar to those of our country. This research is based on the study of the use of root micropiles using mortar injections that are used to reinforce the foundations of existing houses that were built on soils with high probability of being affected by the phenomenon of seismic liquefaction in the Samborondón area. For further development of the research, a geological study was carried out based on different authors of stratigraphic soundings acquired from the research area in Samborondón, from which we were able to obtain results that proved the presence of liquefiable soils within the established study area. Finally, breakage tests were performed on the mortar specimens designed in the Soil Laboratory of the School of Engineering; and subsequently tested at CEINVES, to verify the high resistance of the root micropiles to withstand seismic loads, gravity and possible settlements of two-story housing structures, transmitting them to a stable foundation and, above all, providing adequate safety, strength and stiffness to the problem of seismic liquefaction.
