A novel two-dimensional mixed fracture–pore seepage model for fluid flow in fractured
porous media is presented based on the computational framework of finite-discrete element …

Cement as the main grouting material is usually used in the plugging and reinforcement of
tunnels and rock slopes. The flow and diffusion mechanism of grout in fractures plays a key …

A slurry diffusion model of a single random-roughness fissure is established to consider the
slurry and geological fracture coupling based on the Navier-Stokes equation. The slurry flow …

Grouting to plug water is a common technical measure for the prevention and control of
water disaster in underground engineering and mines. However, the current research on the …

In this paper, we present a three-dimensional (3D) grouting model based on the combined
finite-discrete element method (FDEM). The 3D grouting model discretizes the problem …

To address the issue of uneven spatial and temporal distribution of slurry viscosity in the
grouting process, we propose a novel numerical method for grouting in flowing water based …

Abstract Analysis of cement grout propagation in water-saturated two-dimensional discrete
fracture networks is presented in this study. A two-phase flow model for Bingham fluids flow …

In this study, an orthogonal array experiment is conducted by using a transparent fracture
network replica. Image processing and theoretical analysis are performed to investigate the …

Purpose The purpose of this article is to understand the current research status and future
development trends in the field of numerical simulation on rock mass grouting …
