title = "Simulation of Rock Hydraulics in Rock Joint by Using Discrete Element Method",
abstract = "This study proposed a method to calculate rock hydraulics in rock joint by merging the Lattice method and the particulate interface model in the particulate discrete element method. The Lattice method builds a Voronoi-cell structure based on particles{\textquoteright} contact, which can be used to calculate fluid transmission between cells; the particulate interface model can modify the results of rock joint simulation in the discrete element method. By combining the above two methods, correct mechanical behavior can be obtained by the particulate interface model, and the fluid transmission in the rock joint can be calculated by using the Lattice model. The theory of the Lattice model and the particulate interface model is first introduced. To validate the correctness of the proposed model, the simulated water head and the variation of flow rate in a single fracture under un-shear and shear conditions are validated by the analytical solution. Finally, a re-meshing technique to handle the variation of pore mesh has been proposed to support the operation of the modified fluid flow algorithm during shearing.",
