Title:
APPARATUS AND METHOD FOR ANALYZING SEEPAGE FLOW, AND PROGRAM
Document Type and Number:
Japanese Patent JP3802510
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize an improvement of an analyzing accuracy in a seepage flow analysis using a crack network model.
SOLUTION: After a baserock to be evaluated is modeled with a crack in the baserock as a crack network model imitated by a disc-like crack pattern, intersection determining between crack patterns in crack network model is performed by obtaining an intersection of a plane A including a crack pattern A and a plane B including a crack pattern B (refer to (A)) while maintaining the shape of the crack patterns (A, B) showing in the crack pattern pair (the crack patterns A, B shown in (A)) to be determined for determination in the shape of a disc, obtaining intersections A1, A2 of the profile line of the crack pattern A and an intersection, obtaining intersections B1, B2 of the profile line of the crack pattern B and an intersection (refer to (B)), and determining the presence or absence of a common part for connecting a straight line for connecting the intersections A1, A2 and the intersections B1, B2 (refer to (C)).
