Abstract
Split grouting is a common method of stratum reinforcement. However, due to the concealment of grouting itself, it is difficult to observe the slurry diffusion of split grouting. Therefore, this paper uses PFC2D software to simulate the split grouting in loess to study the diffusion law of slurry and the change of formation porosity. The research results show that the number of fracturing cracks increases with the increase of time. The porosity of soil mass changes obviously after the first fracturing, and the change rate of porosity increases after the second fracturing. With the increase of the initial grouting pressure, the number of splitting cracks is increasing, and the change rate of soil porosity is also accelerating.
