    Evaluation of a micropile laterally loaded using semiempirical, analytical and computational models for geotechnical engineering practice. Case of study: Sabaneta
    (Universidad EAFIT, 2017) Villegas Negrete, Luis; Prieto Salazar, Jorge Alonso
    The Aburrá Valley’s demographic increase has risen house offering -- To tackle this local issue, recently the use of micropiles have spread widely, even though this system has proven to be a reliable alternative foundation to support vertical loads, its capacity to support lateral loads has always been a concern -- Considering this, this research focuses in the evaluation of the behavior of a type D micropile’s laterally loaded -- Two lateral load tests results are consigned and one of them is compared with results obtained from conventional methods used in practical engineering for lateral displacements estimation: semiempirical formulations, P-Y curves and three-dimensional finite element models -- The geotechnical parameters selection implications for the micropiles type D lateral displacement evaluation using semiempirical methods and P-Y curves are analyzed and briefly discussed -- To recreate the triaxial tests stress-strain curves, some of the most practical constitutive soil models currently applied are revised -- To evaluate the implications of the micropile injection process in the micropile lateral displacement estimation, a three-dimensional finite element model is used -- Some alternative proposals for evaluation of the elastic behavior of a micropile laterally loaded are presented -- Finally, conclusions are included, and some research topics are suggested
