【 摘 要 】

The research was conducted on the effectiveness of modern geotechnologies providing minimal soil mass deformations under historical buildings and monuments renovated with underground part development. Analysis of the worldwide experience in renovation of historical buildings and architectural monuments revealed trends in application of geotechnologies concerning underground part development. As a result of numerical experiments with a use of PLAXIS and MIDAS GTS software conducted in 2D and 3D for Moscow typical geology conditions and on-site deformation measurements during renovation of historical buildings with underground part development the method for the settlement prediction at the initial phase of design was proposed. For engineering calculations the graphical interpretation is presented describing the settlement formula for buildings with foundations underpinned by jet piles during the underground floor construction. Recommendations have been done for applying geotechnologies in renovation of historical buildings and monuments with underground part development.
