Precision assessment of mathematical models of facilities as per stress-strain state observation results
There are two main methods of simulation precision assessment: the first - is based on considering uncertainties in initial data for simulation; the second - is based on comparison of checked parameters of facilities observed in the field with their model values. This work includes arguments for selecting second of the listed methods and assessment of error in simulation of deformations and stress of Sayano-Shushenskaya HPP dam.
