This surface imposes the condition that there is a finite population represented by the isolated elements of the foundation. This work presents an analysis of a statistical adjustment of the sample when estimating the population&#8217;s parameters and using the order statistic concepts. The resistance values and the analyzed foundations that were solicited were based on data published in the technical literature in which the resistance variable was measured from load tests. The number of tests in situ concludes, specifically that, for the diversity of the analyzed foundations, the order statistic can be a sufficiently useful tool to estimate the failure probability of pile foundations in cases in which the number of load tests are smaller.]]></p></abstract>

Este trabajo presenta un análisis de la adaptación de la estadística para estimar los parámetros poblacionales, usando los conceptos de la estadística de orden. Los valores de resistencia y solicitación de las fundaciones analizadas se basaron en los datos experimentales publicados en la literatura técnica, donde la variable resistencia fue medida por medio de pruebas de carga. El número de ensayos de campo indica especialmente que, para la diversidad de las fundaciones analizadas, la estadística de orden puede ser una herramienta bastante útil para estimar la probabilidad de falla de fundaciones con pilotes, cuando el número de pruebas de carga es pequeño.]]></p></abstract>
