Environmental approaches when determining the calculated hydrological characteristics

IOP Conference Series Earth and Environmental Science, Journal Year: 2021, Volume and Issue: 839(4), P. 042079 - 042079

Published: Sept. 1, 2021

Abstract The issues of forecasting dangerous hydrological phenomena in water bodies the presence hydrometrically observed data are considered. analytical distribution functions annual excess probabilities applied - sufficiency curves. features calculating empirical probability exceeding characteristics, variation coefficients and asymmetries for distribution, scattering estimates other parameters In case heterogeneity initial hydrometric observations, when series under consideration consists heterogeneous elements regime, curves set separately each homogeneous totality. Based on considered data, a system monitoring emergencies nature at is being constructed.

Environmental measures to reduce air pollution on the territory of a specialized facility

Modeling of systems and processes, Journal Year: 2022, Volume and Issue: 14(4), P. 21 - 28

Published: Jan. 8, 2022

A detailed narrowly focused survey was carried out on one of the three zones technological infrastructure a specialized facility - hangar for aircraft (LA). general list pollutants (SV) released into atmosphere at 2nd site special established. Generators – installations and constructs polluting components specific area stationary mobile type, which operate facility, are fixed in selected sectors. In accordance with nature emission source (stationary or type), is divided 4 The measurement by sectors implemented concentration emissions calculated according to recommended regulatory acts Russian Federation. Indications number substances above regulated MPC 2 energy test have been connection recorded results, techniques procedures organizational technical regulations that contribute minimizing accumulation (gases) functioning engines analyzed recommended. method attenuation near-Earth smoke an interval up two meters from surface where proposed based analysis environmental measures facilities. variation orientation outflow gas flows during launch, taxiing, takeoff, landing, passage (VS) along airfield track.

Analysis of defects in supporting structures of an industrial building

Modeling of systems and processes, Journal Year: 2022, Volume and Issue: 15(1), P. 14 - 24

Published: April 8, 2022

All buildings with a significant service life must be regularly surveyed. This work analyzes the results of inspection building compressor shop KC-1. Analysis design documentation and measurement showed that structurally has overall dimensions in plan along outer axes 21.0 × 72.0 meters. The height is 17.0 conducted visual examination presence damages defects third fourth categories, which requires an instrumental examination. In particular, need to determine strength brickwork concrete structures. analysis showed: testing wall masonry by shock pulse method using ONIKS 2.5 device compressive grade silicate brick walls corresponds M75 M125, ceramic M100. mortar for M50 M75; non-destructive control DigiShmidt2000 class reinforced columns workshop B20, girders B25, floor slabs coating B20. Verification numerical calculations on computer bearing capacity structures were performed taking into account actual static diagrams, sections elements, characteristics materials established during survey, constant loads existing at date survey. Based verification calculation transverse frame building, it was found upper chord truss not provided. when calculating according first second groups limiting states general, technical condition KC-1 unacceptable.

The process of surveying the technical condition of the building of the elevator of the silo building

Modeling of systems and processes, Journal Year: 2022, Volume and Issue: 15(4), P. 34 - 43

Published: Dec. 13, 2022

This article is devoted to the analysis of technical condition building and structures silo elevator on basis survey. The state foundations, walls, ceiling columns installed at corners height shown. purpose study was a visual inspection reinforced concrete load-bearing elevator. Some results performed instrumental studies materials facility are given. Defects damage main general hull were identified visually. An showed: walls have “limited operational condition” - there signs violation working capacity bearing structures; farms "limited condition" capacity, coating has structures. as whole assessed “workable condition”. phase period operation determined. Recommendations been developed ensure safe under study.

Simulation of scenarios for the development of a fire in a shopping and entertainment center

Modeling of systems and processes, Journal Year: 2021, Volume and Issue: 14(3), P. 50 - 59

Published: Sept. 22, 2021

The paper analyzes fires in the Russian Federation, including shopping and entertainment centers. Objects with a mass stay of people are investigated on example center Passage "Solnechny Rai" Voronezh. As result analysis carried out study objects massive presence people, our case, at alleged object extinguishing fire conducting an ACR, time there were more than 50 one way or another comparison even night when no , refers to people. Forecasting development was for Rai". Simulation two scenarios most dangerous zones occurrence has been out. According first scenario premises Perekrestok store located ground floor, event store, greatest amount manpower resources will be required, since this facility highest load, storage large goods. second scenario, breaks retail space third floor building “Solnechny Rai” center. fire, adjacent rooms higher floors quickly filled combustion products, which lead impossible evacuation by their own forces. For considered center, recommendations have developed organizing rescue operations.
