COMPARATIVE ANALYSIS AND PERSPECTIVES OF TECHNOLOGY DEVELOPMENT CONSTRUCTION OF PREPARABLE-MONOLITHIC GLASS-TYPE FOUNDATIONS

Abstract

The prospects of developing a semi-precast technology for constructing pocket-type foundations are considered. A collection and analysis of previous publications have been conducted. An evaluation of the current state of semi-precast pocket-type foundation technology has been made, outlinied its advantages in comparison with alternative precast and monolithic construction technologies. The main problems and prospects for further research of the technology have been identified. Several structural-technological solutions for semi-precast foundation construction have been presented, describing the features of each solution, identifying the advantages and disadvantages of their application in construction. The technological solution been viewed as a system from the perspective of system analysis principles, identified the main factors as subsystem elements that determine the technological aspects of each solution. Rules for identifying factors that influence the choice of structural-technological solutions have been outlined, using the example of studying the process of constructing semi-precast foundations. A sequence of actions for constructing a system of factors and criteria has been provided. Several criteria have been selected from subsystem elements as factors for comparative analysis and evaluation of structural-technological solutions. A comparative analysis of the effectiveness of the semi-precast technology and structural-technological solutions based on selected technological criteria has been provided in comparison to monolithic and precast technologies. A comparative analysis of technologies and structural-technological solutions based on the criteria of the system has been conducted, and the results have been systematized for further evaluation. The key differences, advantages, and disadvantages of each solution have been identified in comparison to alternative solutions, outlining the quality characteristics of the identified factors in application of given solutions. The most promising solution for further research has been identified and justified.
