Modeling and Characteristic Analysis of Pulsating Grouting System Based on AMESim
In order to understand the mechanical characteristics of the pulsating grouting system and the control characteristic of pressure and other parameters,through the analysis of the composition and working principle of the pulsating grouting system,a simula-tion model of the pulsating grouting system was established based on the AMESim simulation platform.In order to verify the correctness of the model,the pressure and flow data of the slurry pipeline monitored at the construction site were compared with the output data of the simulation model.The results show that the simulation model can accurately simulate the dynamic curves of the system,and the aver-age relative error of pressure and flow are 6.4％and 7.6％respectively,which verifies the correctness of the model.According to the change of grouting conditions,through simulation model analysis,the change curves of the pressure and flow characteristic in the slurry pipeline are obtained under different pumping frequency,slurry viscosity,pipeline length and other conditions.
