Research on Numerical Model Construction and Seepage Characteristics for Karst Water Based on Three-dimensional Random Fractures
摘要
Abstract
In order to study the micro dynamic characteristics of karst water in fractured aquifer media,the rock cores of Ji'nan Quancheng Park are used as samples,and the internal fracture structure information of the aquifer medium is obtained through CT scanning and 3D reconstruction technology and the internal three-dimensional fracture structure is reconstructed.A three-dimensional network of fractured water containing media is constructed using Monte Carlo simulation technology,and the numerical simulation method is used to study the seepage characteristics of karst water in fracture network space.The results indicate that the micro heterogeneity of karst fractures in the study area is strong,the seepage is controlled by the distribution of cracks and has strong directionality,and the seepage velocity at the intersection of cracks is much higher than that of other parts.关键词
