Matviichuk I. PLANNING OF UNDERGROUND SPACE OF MEGACITIES IN THE CHANGING GEOLOGICAL ENVIRONMENT

The modern development of megacities is accompanied by extensive development of georesources and leads to a significant complication of the functional and spatial organization of the city. One of the most effective ways to solve urban problems (territorial, transport, energy, environmental, water supply, as well as preserving the architectural identity and cultural heritage of cities) is the construction of underground structures and multifunctional complexes for various purposes using advanced geoengineering technologies. Among the problems of planning the underground space of large cities, the tasks of the impact of variability of the geological environment on the stability of underground structures and the forecast assessment of its favorable construction and operation of underground facilities remain significant. The purpose of the dissertation research is a systematic substantiation of the planning of the underground space of megacities in a changing geological environment. A set of methods of theoretical and experimental researches, in particular the modified method of morphological analysis, a method of expert estimations, a method of finite elements and a Monte Carlo method (and also their synthesis), a technique of field inspections of a technical condition of underground constructions, a technique of laboratory definition of physical properties are used. soils (according to DSTU B B.2.1-17: 2009), etc.
