Abstract

Purpose.  Scientific  research  of  the  causes  of  the  numerous  accidents  in  the  calculation  and construction  of  the  deep  foundation  pits  in  the  conditions  of  the  compact  urban  development. Methodology. The accidents in the foundation pits more than 15 meters depth were selected as a material for the analysis. Findings. Aftercarrying out the analysis of the various errors that leads to the accidents, the main causes and consequences of these accidents have been investigated. Three main groups of causes of accidents were classified as: errors in carrying out of the geological, errors in the calculation and designing, and errors in the construction and the irregular running. Also the subgroups of  errors  have  been  identified with the examples  of the accidents  have  happened  in  the  world. Practicalvalue. The  article  presents  the  results  of  the complex  analysis of the accidents  in deep foundation  pits and  their consequences. The main causes of the destruction of foundation pits were classified, which allows increasing the level of the understanding on the issue of the accidents in deep foundation pits and avoiding making similar mistakes in the future.
