Abstract

It is possible to ensure safety of the entire construction process as well as safe operation of buildings and structures in future by timely implementation of geotechnical monitoring. Geotechnical monitoring of buildings and structures is a complex research of “soil base – foundation – above ground structures of a building”. Geotechnical monitoring studies behaviour of buildings and structures during construction and operation and, safety measures to prevent hazardous situations in future are undertaken upon analysis of acquired results. Geotechnical monitoring comprises combination of works, including field observation for structures’ behaviour of a building under construction or renovation, its foundation, including soil body surrounding the structure under construction, and field observation for structures of surrounding buildings. Such monitoring allows us to timely detect and prevent non-reversible processes that occur in “soil base – foundation – above ground structures of a building” system. Considering task in hand to ensure safety and security of buildings and structures, list of geotechnical monitoring works can be divided into following blocks: object monitoring; hydrogeological monitoring; ecological monitoring and computational and analytical block which makes assessment of current geotechnical situation on the construction object and develops relevant recommendation for further continuation of works. This article looks into special aspects of multiyear (2005 – 2019) geotechnical monitoring for deformational behaviour of buildings under operation, open parking spaces No.1 and No.2, located in area of effect from construction of railway connecting Vnukovo-1 airport and Kievskiy train station in Moscow and in the area of effect of new Vnukovo-1 airport construction. Article looks into tasks to ensure regular operation of existing buildings and monitoring of hazardous situations and their origin caused by construction works or poor technical condition of monitored objects. Particular to renovation of Vnukovo-1 airport, that started in 2005 is the fact that during construction it was necessary to ensure operation of a number of maintained buildings. Among them are open parking spaces No.1 and No.2.
