Abstract
From the point of fracture morphology, certain characteristic form is produced with growing fracture segments and their jogs, such as en echelon, shear lenses and flower structure, so that segmented structure makes a fault line discontinuous at around jogs, place to place. Based upon such morphological aspect, we can understand better the natural structure of fracture system, and hence, we might estimate better the actual hydraulic field that affects much on the flow of groundwater and mass transport.
In this paper, the authors try to reconstruct the segmented structure of fracture zones around the large rock caverns, utilizing detailed description of fault occurrences obtained on the cavern walls. The fracture occurrences are classified into 7 patterns, and adding fracture geometrical information such as strike and dip, the segmented bodies and jogs are identified. The segmented fault structure map is presented, and its appropriateness is checked and discussed.
