Process of Micro-Simulation of Infilitration Clogging for Highland Reservoir Dam Foundation

Abstract:

Using of numerical models of particle flow are based on discrete element theory, combining with the indoor infiltration clogging tests in the region of south mountain in Tibet, the whole development process of the infiltration clogging of loose foundation is simulated. The loss volume, fluid velocity，osmotic coefficient, porosity and moving track of particle samples are recorded and traced in the analytical model, which reveals the water-soil interaction throughout the whole process of the infiltration clogging. The results show that clogging often occurs in the upper soil. Particle trajectory is random reveals the certain randomness of formation of pores. Results of simulation are consistent with the indoor test, to some extent, which validate the feasibility of numerical method in infiltration clogging research. These results provide certain useful data for the further study of infiltration clogging, and also provide a new way for interpretation and analysis of penetration clogging phenomenon in micro-scale .
