The article considers the issue of integrated assessment of various geo-protective technologies that can be used in a cold region. For the first time, a parameter is introduced that takes into account the effect of negative temperature on the work of the tecnology being introduced as a whole. Materials for construction can also be assessed by the above algorithm. The calculation ends with a PQ index for each object.
The article aims to increase the bearing capacity of the base by means of using reinforcement. A comparative analysis of the impact of different types of rein-forcement on the deformation characteristics of the soil in the Northern climatic zones is carried out. In this article, the parameters of clay soil were considered, which were used to calculate the optimal method of stabilization of the building. The value of the study was justified, despite the fact that clay soils have a high strength index, without additional design solutions, seasonal freezing and thaw-ing can lead to an emergency.
At design supporting structures for coatings of transport buildings and structures for northern areas in accordance with regulatory requirements, their resistance to progressive (chain) collapse is determined. To ensure safety, the structural system of the building in the northern areas must ensure its durability and stability, at least for the time necessary to evacuate people. To improve the reliability of the supporting structures of coatings proposed, developed and researched the system of redundancy of the type-sprengel. The scenario of collapse and an algorithm for calculating the intact elements of the coating system are proposed. The results of the study are given, which indicate that by varying the rigid parameters of the backup system it is possible to achieve minimal damage from the collapse of individual elements of the system.
In article questions of influence of wooden cross ties on a surrounding medium in the course of their operation on the railroad and after their replacement are considered in cold northern regions. The biggest negative impact on the environment comes from wooden sleepers impregnated with coal oil, oil pollution and heavy metal ions. Some ways of isolation of waste wooden cross ties by means of the geoeco-protective spreading materials are shown. Insulation technology has been proposed to minimize the environmental impact of spent wood sleepers for cold areas.
One of the most effective types of modern building structures are combined systems sprengel type for cold areas and aggressive environments. Structurally, they consist of a stiffening beam reinforced with one or several pre-stressed flexible elements - ties. The practice of designing such systems has shown that the greatest efforts in a stiffening beam arise under the action of non-equilibrium, including one-sided loads. To solve this problem, a technique based on the use of heuristic optimization methods has been developed: a genetic algorithm and an annealing simulation algorithm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
