Abstract
The diaphragm wall of deep circular shaft is needed to construct a building structure in great depth of large city. The diaphragm wall of deep circular shaft designed lateral pressure is no evidence on scientific fields. From the measurement results of earth pressure gauge and water pressure gauge and reinforcement stress gauge are located on the field, the uneven lateral pressure acting on the diaphragm wall of deep circular shaft, the main factor is bias of water pressure. It is clarified by Iwanami et al. However, design water pressure of current deep circular shaft is adopted as hydrostatic pressure or pore water pressure. Therefore, in this study, is comparing and confirming the measurement results that validity of design water pressure by 3D seepage flow analysis, performing structural analysis for the design water pressure distribution, showing aptitude of design load, proposed the setting method of the design water pressure.
