摘要：
FIELD: measurement; testing.SUBSTANCE: invention relates to the study of water-containing geological structures. Disclosed is a method for determining structural discrimination indices of an ordovician limestone top filling zone, according to which: first, three types of filling zone structures are determined, specifically, a continuous filling structure, an intermittent filling structure and an unfilled structure; then the discrimination indices are determined in accordance with the three types of structures of the filling zone, including: the q value of water breakthrough to the well, the flow rate Q of the groundwater and the coefficient K of permeability of the ordovician limestone section; then, respectively, the threshold values for each index are determined in accordance with different waterproof properties corresponding to the three structures indicated; wherein the indices are obtained through several stages on the basis of calculation from the given ratios of the magnitudes of the water breakthrough
