Calculated evaluation of shoring of deep excavation in the restrained urban conditions (Khabarovsk, Russia)

Abstract

The paper presents an evaluation of geotechnical state on the project construction site and an evaluation of deep excavation impact on the current site development. It also provides an optimal design for the deep excavation, an impact analysis of horizontal shifts in the poling, an assessment of bending moments in the poling and the stresses in the sprung design. The numerical modeling was carried out for developing variants of the deep excavation as well as a preliminary assessment of the impact that the project underground construction produces on the surrounding buildings and constructions. Some recommendations on choosing a reliable variant of the undergrounds arrangement and the engineering operational technology are suggested. The paper offers the results of geotechnical monitoring of the building deformations nearby and in the shoring of deep excavation during the underground construction.
