NEW METHODS OF MEASURING BUILDING DEFORMATIONS AND CRITERIA FOR THEIR ESTIMATION

摘要

For buildings located near underground excavations (trenches, tunnels), the curvature of the lower surfaces of their foundations, which can be calculated by analytical means on the basis of measurement of building settlements by the geodetic method, as well measurements of the angles of incline of the foundations by the method of microleveling, is proposed for use as a basic criterion for estimation of their deformations. Use of both methods is examined for determination of the curvature of the lower surfaces of building foundations falling within the construction zone of the tunnel and elevated segments of the third transportation beltway in the Lefortovo section of Moscow for purposes of evaluating the operational safety of their structures.
