Resumo: | |||||||||||||
This work presents a computer implementation for finite
element analysis of excavation problems and unconfined
steady state flow through saturated soils. These computer
routines are particularly useful for the study of earth
dams and they were written with the aim to pursue the
development of a numerical model (Parra, 1996) devised to
investigate the behavior of earth dams under static and
seismic loading. Two techniques were implemented for
excavation simulations, with both yielding the some
numerical results. For the unconfined fluid flow problem
the technique proposed by Bathe and Khoshgoftaar (1979) was
adopted, which recasts the problem in a non-linear form but
keeps the same basic finite element mesh. The results
computed in this research were compared with other
analytical and numerical values published in the
literature, in order to ensure, as much as possible, the
feasibility and efficiency of the computer implementations.
The behavior prediction of the Macusani earth dam, to be
built in Peru, was also studied in this research, focusing
on several aspects related to its planned construction: the
excavation, the construction itself and the first reservoir
filling. This results may eventually be useful for the final
engineering design of the Macusani dam.
