Abstract
Sometimes, it is necessary to build a subsidiary weir downstream the heading-up structures to relief the acting head. In the present study. Water prevented between the main and subsidiary structures was considered. The boundary element technique using linear elements was used to analyze the uplift pressure underneath a simple flat floor of the heading-up structure and the subsidiary weir. Seepage flow and the exit gradients were also considered. Seven cases of the distance between the heading-up structure and the subsidiary one had been considered with five thickness of the permeable layer under the structure. Obtained results were illustrated and discussed.
