Prospects of underground parking during the reconstruction in the center of St. Petersburg

Abstract

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.

Construction of Underground and Multi-story Car Parks in High-density Urban Areas

“…When constructing buildings and structures in dense urban areas, it is necessary to take measures to monitor the condition of buildings and structures located near the object under construction. To do this, terms of reference are drawn up, which should contain a rationale for monitoring operations, goals and objectives, parameters of the newly constructed building, parameters of existing buildings and structures within the area of influence, geotechnical conditions on site, and technical monitoring requirements (19)(20)(21)(22)(23).…”

“…Often it is not easy to comply with all the requirements, and therefore the construction of underground parking should involve professionals (11,12) The most important characteristic of the site for building an underground parking lot is the hydrogeological conditions, in particular, water currents and soil composition. The problems of stabilization of weak soils in Russia were studied by many research scientists (13)(14)(15)(16)(17)(18)(19)(20)(21). Numerous works by Dashko et al (22) are devoted to the issues of justification of building construction in complex engineering-geological and hydrogeological conditions of St. Petersburg.…”
