Abstract: Accuracy improvement the and convergence of the solution of finite element problems are of interest to many scientists. The Biot consolidation theory is used to investigate the adaptive time steps in the construction process, water accumulation and operation of local material dams which is designed according to Cam-Clay material model. From the principles of Biot consolidation theory, basing on energy errors control to provide time steps to control effective stress field as well as pore water pressure in the body and foundation dam. The investigation is very significant for the construction of local material dams, especially for dams using embankment material with high clay content such as Dak Yen dam in Vietnam.
Keywords: Adaptive Time Steps, Error Control, Local Material Dams, Dak Yen Dam.
