QUANTITATIVE INTERPRETATION OF THE HORIZONTAL GRAVITY GRADIENT FOR SEMI-INFINITE HORIZONTAL SLAB STRUCTURES ACCORDING TO DATA FROM STATISTICAL ANALYSIS

applied method for quantitative interpretation of the gravitational field caused by semi-infinite horizontal slab structures is based on the horizontal gradient U xz distribution on different levels. Representative characteristics are chosen, that can be obtained without ambiguity from the data after analysis of the measured gravitational field - the maximum value of the horizontal gradient Uxzmax, the anomaly width ∆ X1/2 for gradient value Uxzmax/2 and the widths of the two branches of the horizontal gradient distribution - ∆ X1/2 − and ∆ X1/2 + . Subject of the study is the relationship between these characteristics and the main parameters of a semi-infinite edged horizontal slab - the depth h1 to the slab structure, the thickness of the slab ∆ h (∆ h=h2-h1) and the angle of the edge α . On the base of statistical studies for a wide range of different model parameters are obtained correlation ties suitable for the aims of the quantitative interpretation.
