SOIL BASE RELIABILITY ANALYSIS BY CRITERION OF SETTLEMENT AT RECONSTRUCTION OF THE STRUCTURE WITH LOAD INCREASE

Abstract

The article describes the methods of reliability analysis for the soil basis by criterion of deformation (settlement) of the foundation before the reconstruction of a structure at a stage of operation and after reconstruction with additional deformations of soil base by SP 22.13330.2011. Methods of reliability analysis of the soil bases by the settlement criterion is based on the possibility theory (in extremely small amount of statistical information on controlled parameters), and combined (possibility-probabilistic) method of reliability analysis with a larger amount of statistical information. Examples of reliability analysis in case of limited statistical information of controlled parameters in design mathematical model of limit state are given. Article can be considered as a manual for estimation of a possibility of reconstruction of a structure with increase in load on the soil base.
