ABSTRACT: In this paper a reliability analysis of shaft constructed using the flotation technique is presented. Ultimate states are evaluated, such as: nucleus stability, excavation stability, bottom uplift failure and floating of finished structure. In order to assess the reliability of the flotation construction system, the point estimate method of Rosenblueth is used. Finally some conclusions are presented.

RESUMEN: En este artículo se presenta un análisis de confiabilidad de lumbreras construidas por el método de flotación en el que se evalúan los principales estados límites de falla, tales como: falla del núcleo central, falla general por cortante, falla de fondo por subpresión y falla por flotación. Se evalúa la confiabilidad de este sistema constructivo mediante el método de estimación puntual de Rosenblueth. Finalmente se dan unas conclusiones respecto a lumbreras flotadas.
