Safety of existing buildings during underground mining

Authors: Konyukhov D.S.

Large-scale and high-rate underground mining in process in the territory of Moscow, in the complex conditions of compact urban development of high historical value face designers and builders with difficult and diverse challenges connected with safety of the existing buildings and structures. The main effective parameters and their influence on the existing building safety are revealed by now. Here belong maximum allowable deformations in the form of maximum subsidence and relative subsidence difference, as well as some characteristics which are nonstandardized, or are governed not by construction standards. The analysis shows no direct quantitative connection between the monitored/measured parameters and structural safety of buildings. Such connection is prevented by: overstated limiting deformation standards for foundations of ground surface buildings and structures during underground construction; incorrect approach to estimating critical deformations of foundations of buildings; standardized approach to deformation of foundations in the influence zone of underground construction with and without pit excavation. The research shows that safety of underground construction in the conditions of urban development requires another approach than the Construction Code SP 21.13330 and SP 22.13330 propose for undermined areas and open pits. It is required: to control the impact exerted by underground tunneling and construction on the environment and existing buildings; to be ruled not by the absolute subsidence value but by the relative subsidence difference and by the foundation foot curvature, which, though complicates measurement, better images the response of building structure to deformation induced by underground construction; to use the modern methods of the soil overcutting coefficient in tunneling.

Keywords: underground construction, foundation foot curvature, subsidence trough, building subsidence, pit excavation method, relative subsidence difference, underground operations, existing buildings, tunnel.
