COMPARATIVE ANALYSIS AND CHOICE OF THE OPTION OF ORGANIZATIONAL AND TECHNOLOGICAL SOLUTIONS OF THE PROCESS OF LIQUIDATION OF THE CONSEQUENCES OF EMERGENCY DESTRUCTIONS

Abstract

Problem. The development of cities and settlements increases the probability of emergency situations of natural and man-made nature, which leads to the occurrence of accidents. The variety of accidents, which are accompanied by danger to people, affects the organization and technology of emergency rescue and recovery works. Military actions increased the urgency of the issue of improving organizational and technological solutions for liquidation of the consequences of accidental destruction. Method. The research of organizational and technological solutions of the process of liquidation of the consequences of accidental destructions showed that such destructions cause a redistribution of the load on the structures and the threat of their repeated collapse. To prevent collapse, structures are reinforced with temporary elements. A systematic approach to the configuration of temporary reinforcement systems allows to formulate the principles of optimization of organizational and technological solutions for liquidation of the consequences of emergency destruction. In order to choose the optimal option for reinforcement, the classification of technical means by structural features and manufacturing material is accepted. Originality. Increasing the efficiency and safety of work on liquidation of the consequences of emergency destruction is possible due to the improvement of organizational and technological solutions for the liquidation of such consequences using typical strengthening solutions and choosing an option for stabilization of extra-design deformations. The availability of a database of typical strengthening solutions and the availability of a calculation model will allow to quickly choose a method of strengthening emergency structures. Practical value. The algorithm allows you to create a database of measures and solutions for the stabilization of a large-panel building that has been affected by overtime load. Filling the database when performing variable calculations will allow to significantly speed up decision-making regarding the stabilization of buildings affected by overtime loads. Optimization of the sequence of execution of works to eliminate the consequences of emergency destruction was carried out for three variants of execution of works using wooden individual, metal typical and combined systems of temporary reinforcement.
