CASE HISTORY: CHALLENGES DURING THE DESIGN AND CONSTRUCTION OF A CELLULAR COFFERDAM

摘要

Projects often face design changes during their construction phase. These changes lead engineers to a series of redesign and sensitivity analysis in order to evaluate their influence. In this paper a series of changes in site conditions and constructions deviations during the construction of a cellular cofferdam in Puerto Belgrano Naval Base (Argentina) are presented. Their effect on overall stability, uplift failure, as well as results obtained for analytical an numerical models are showed.
