SUBSTANTIATION OF RATIONAL METHODOLOGY AND MEASURING ACCURACY FOR YIELD OF CIVIL AND INDUSTRIAL BUILDING AND STRUCTURE FOUNDATIONS

Abstract

The paper demonstrates that while measuring yield of civil and industrial building and structure foundations the geometric leveling is carried out rather often with unjustifiably extra accuracy. Calculative examples of the required accuracy of leveling measurements are given on the basis of criteria in respect of maximum allowable skewness of building structures in a vertical plain. The paper proposes to include a statement in a normative document that permits to apply inequality in respect of length of sight with its compensation in leveling line and correspondingly introduce exclusive standards to accuracy of a leveling alignment on horizontality of a directional ray.
