Abstract

The importance and necessity of using underground spaces in the present era is not overlooked. Caverns are used as an important bunch of underground spaces for the storage of radioactive waste, hydrocarbons, and hydroelectric power plant projects. Construction of Caverns has particular complexity and water seepage into the Caverns is one of the most important problems. The purpose of the present study was to investigate the 3D modeling of the fracture network of a Cavern for the pumped storage power plant of Rudbar Lorestan dam by using DFN method and 3DEC software and then determining the tensor of hydraulic conductivity by using the model. To achieve the goal, statistical analyses were performed on the in situ data extracted from the area. Power law distribution was determined as a suitable statistical distribution proportional to the data. Then, the DFN model was created and validated using the Watson-Williams test. In the following, a block model of DFN made from the fractures was constructed to determine the Representative Elementary Volume for different dimensions from 1 to 12 m. It was found that a 7-meter model was appropriate. Furthermore, the tensor of hydraulic conductivity was determined by using a hydraulic head on a generated REV.
