    Abstract
  • Based on the spatial distribution characteristics of karst, the horizontal uneven distribution and vertical zonation characteristics of karst were summarized, and their impact on karst rate statistics was analyzed. Based on the investigation data of a buried sewage plant, the vertical zonation of voids and line karstification rates were analyzed. Furthermore, the probability relationship between the statistical data of borehole porosity rate and liner karst rate was analyzed according to the principle of sampling error. It is considered that the horizontal heterogeneity and vertical zonation of karst development, as while as the actual number of limestone holes and the depth of rock drilled, should be taken into account in each exploration stage. Therefore, the karstification rate is effectively estimated using interval estimation.
