The problem of constructing a continuous model of a hierarchical-block geomedia is considered. The basic structural element providing the geomedia structuring is determined, and the transition from a hierarchically blocky to a hierarchically structured media is discussed. The introduction of four structural levels is sufficient for the geomedia mod...

Hierarchically block character of a constitution of geomedium is now recognized by the majority of researchers, and a search of adequate mathematical models of such medium is the actual problem demanding the prompt decision. In this direction, it is possible to emphasize two basic approaches, caused by the proposed principles of modeling.

Some approaches to the simulation of hierarchically-block geomedia are considered. The idea of mesomechanics with allocation of mesovolume of representative scale level is used. It is offered to describe within the frame of geomechanics a rock mass four scale levels considering the conforming hierarchy of structural blocks. On each of these levels...

Decrease in risk of catastrophic consequences of the geodynamic phenomena of phylum of rock bursts or earthquakes demands the development of prognosis base of these events. Research of laws of formation and development of mesocracking structures on rocks samples is the most effective path of dilating of representations about mechanisms of the geody...

Contemporary rock mechanics is based on the principals of classical Continuum Mechanics theory. But new experimental results such as “zonal disintegration” around deep openings and “reversible deformations” of highly compressed rock samples cannot be described correctly from this viewpoint. A new approach to rock mechanics mathematical models consi...

A principal difficulty with island megalopolises is the transport problem, which results from limited surface land on an already developed island, on which roads and car parking can be placed. This limitation leads to traffic jams on the small number of roads and to intrusive car parking in any available surface location, resulting in safety issues...

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 megalopolis...

New experimental results such as “zonal disintegration” around deep openings and “reversible deformations” of highly compressed rock samples cannot be described correctly from contemporary rock mechanics, which is based on the principals of classical Continuum Mechanics theory. A new approach to rock mechanics mathematical models consists of the ap...

Studies of brittle rock samples failure were carried out in Laboratory of Geodynamics of Far-Eastern University, Vladivostok, Russia. It was assisted by servocontrol loading machine MTS-816, acoustic emission (AE) complex, and multi-channel complex. The regularities of formation and development of dissipative mesocracks structures in rock samples u...

Deformation of rock samples compressed up to failure has been studied in laboratory. A system of trustworthy deformational precursors of the failure stage has been developed. The system includes long-term, middle-term and short-term precursors, which correspond to the threshold of dilatancy, change of the specific volume deformation, and jump of th...

The problems of the use of underground space in Vladivostok city are discussed. It is clearly explained that in mountainous conditions areas the road tunnel system can be effectively used to improve the difficult transport situation. The existing city network of roads cannot satisfy the criteria of transport stability, safety and ecological securit...

Rock mass damage at great depths near underground openings is often of a zonal character. However, the classical elastoplastic theory fails to explain sufficiently all properties of zonal failure structures. A new non-Euclidean mathematical model for highly-stressed rock mass was developed based on the principles of mechanics of defected material a...

The search for reliable methods of forecasting macrofailure is one of the basic problems of modern geodynamics. This problem depends to alarge extent on the possibility of determining reliably defined precursors of failure (Sagiya 2011). Till now, these have been considered to be a rise in the acoustical activity of rocks and mass and large anomalo...

The experimental results are presented for deformation of rock samples in the pre-failure zone under compression. Anomalous periodic character of change in strains is established. An elastic solution to the corresponding problem on the anomalous behavior of rock samples is found, and the experimental databased phenomenological parameters of the mod...
