Two approaches for the description of parameters of the trough of the land surface subsidence in the main sections (its forms, inclinations and curvature) are considered in comparison with each other. One of them, (the method of standard curves) makes up the basis for “Rules of the structures protection...”, the document defining the approach to the assessment of deformation of the day surface during design of various facilities, located on it. Besides, the approach, developed in some other works by the authors, based on the approximation of the form of the trough subsidence with the functions of the probabilities integrals type with three defining parameters, is considered. The attempt to express the standard curves as the mention functions is undertaken. It is proved that it is possible to define the values of three corresponding parameters of the approximating functions. Thereby the tabular dependences are transformed to the analytical relations, correct for all the range of the parameters change, i.e. not just for those, recorded in the tables.
