“…Due to these factors sometimes it is impossible to perform monitoring inside the underground facility, which in its turn reduces integrity and trustworthiness of the structural state assessment. It is especially relevant as far as the spatial behavior of the structure is concerned, when the maximum tensile stress appears in the bottom zone of the tunnel that is beyond the reach of visual and instrumental control [9]. It should also be noted that during the tunnel operation period this kind of stress can result in the lining consistency defects, which can lead to water leakage outside the lining and further expansion of soil and -in the long runadditional soil settlements.…”

The article offers an information about the work carried out on technical monitoring of the city sewerage system tunnel in the framework of the actual problem of recreating the objects of cultural heritage of St. Petersburg, which fall into the protected zone of underground engineering networks. The purpose of the study is to identify values of the stress-strain state of the tunnel lining at various stages of construction of a cultural heritage object located on the earth’s surface in the immediate nearness. For formation of a base of the analyzed values was undertaken geolocation of ground massive, conducted geodetic measurements, defined the deformation of the soil by inclinometer boreholes, was obtained graphs of precipitation the soil massive, developed by setup technology for strain gauge sensors linear displacement inside the tunnel, worked out the mathematical model in the specialized software. Analysis of the obtained results allowed us to associate values of the stress-strain state of the collector tunnel effect from the buildings under construction and structures, as well as to identify the actual task for further research to develop methods of rapid diagnosis of the stress-strain state of tunnel lining structures in terms of their special mode of operation.

The aim of the work is to assess the possibility of underground parking during the reconstruction of objects located in the historical part of St. Petersburg. Using theoretical research methods, an analysis of typical problems during reconstruction with the development of the underground space is carried out, widely used work production technologies are identified, and the experience gained from such construction in St. Petersburg is evaluated. The result of the study was the conclusion about the possibility of constructing in-depth and semi-in-depth parking lots, as well as the reconstruction of existing buildings with underground parking in the central historical part of the city. At the same time, a high probability of significant restrictions or even a ban on reconstruction was noted. In addition, under the constrained conditions of historical development, high-quality, thorough and systematic implementation and monitoring of repair and construction work by professional geotechnicians and builders is required.

This study presents two field cases of deep excavation using the hydraulic servo geotechnology as an enhancement to the lateral support. The first excavation process was preceded with numerical simulation to investigate the deformation of excavation pit with and without servo geotechnology. Optimised axial loading capacities from the numerical simulation were adopted at the actual excavation site. On the second excavation site, servo geotechnology was applied directly on the excavation process during actual construction without prior numerical simulation. The results showed that the servo steel support geotechnology restrained above 70% of lateral displacements of the excavated walls, and ground surface influence zone settlements were kept within the acceptable warning limits. Prior application of the numerical simulation before field excavation optimised axial loads and kept the deformation caused by excavation within project limits. The numerical simulation of servo geotechnology deformation control capacity for deep excavation projects is validated, and this study provides a practical and significant reference on similar projects.
