- Reinforcement effect of cement grout injection on soil was studied using PFC2D numerical simulation test. The effect of cement particle size distribution, soil particle size distribution and the parallel bond strength between particles on mechanical properties of cement soil after reinforcement was analyzed. The stress-strain curve and the ultimate bearing capacity of cement grouting soil were studied by the numerical tests. The results show that under the same amount of cement, the cemented soil with small cement particle size shows a higher ultimate stress and a larger strain corresponding to the ultimate stress. The ultimate stress increases slowly with the decreasing particle size under a certain range. Ultimate stress of the cemented soil increases with the increase of the parallel bond strength. In addition, the cemented soil with large parallel bond strength shows a larger strain corresponding to the ultimate stress.
