Abstract
Necessity of formation of the uniform concept of maintenance of development of the megalopolises, combining building of aboveground and underground complexes is shown. Interaction of elements of geotechnical system ≪a megalopolis - an underground construction≫ with a view of maintenance of ability to live of underground constructions of megalopolises is considered. Classification of conditions of development of megalopolises by stage of use of the underground space, added with criteria of reliability, safety and an economic optimum is developed. Conditions of maintenance of ecological compatibility and infrastructural appeal of megalopolises, as centres of cultural and commercial development are considered. Necessity of formation of the general scientific discipline ≪Megalopolises Geotechnics≫, covering a complex of methods of aboveground and underground building of megalopolises taking into account reliability and safety of functioning, ecological compatibility, infrastructural appeal, and also an economic optimality answering to criterion is formulated.
Highlights
Development of megalopolises in modern conditions demands a comprehensive approach considering both the characteristics aboveground, and underground building, bound among themselves principles of reliable and safe functioning at the optimum economic decision Such approach in case of a megalopolis locating in island terrain where the aboveground space is circumscribed by the connatural factor - a coastal line is especially important
As well as any complex system, it as becomes to vulnerable and subject system failures [5]. In this connection carrying out of the researches defining at a modern level of development technicians and technologies of optimum design data of a uniform geotechnological complex taking into account their area, number of storeys, appointments, completeness of use, influence on formation, maintenance and development of objects of a city infrastructure of a megalopolis for the purpose of rational geographical demarcation of underground space and specialisation of underground constructions is necessary
The research made within the framework of complex development of underground space of the Vladivostok City, consists in working out of procedures of definition of rational parametres of underground constructions taking into account their interference and means of maintenance of the working space
Summary
Development of megalopolises in modern conditions demands a comprehensive approach considering both the characteristics aboveground, and underground building, bound among themselves principles of reliable and safe functioning at the optimum economic decision Such approach in case of a megalopolis locating in island terrain where the aboveground space is circumscribed by the connatural factor - a coastal line is especially important. Classification of conditions of building by principles of a sustainable development [2] becomes the important factor of regulation of use of underground space of megalopolises. Other principle it is maximum an effective utilisation of underground space (compactness of a locating of underground constructions in relation to each other and terrestrial surface at observance of the first principle). Both first conditions should answer to a principle of the minimum cost of building. Definition of the specified principles shows that the existing contradiction between requirements of the minimum cost and peak efficiency leads to a problem of optimization, which should be resolved in each specific case with application of classification and mathematical approaches
