【 摘 要 】

Simulation of concrete pouring progress has been done for cast-in place pile. ICEM was used to geometric model establishing and grid generation. Fluent was used to fluid model establishing and calculating. Results show that pressure appears when concrete arrives and reach the largest when concrete is tanked up. Eddies appear at the beginning of pouring but will not be obvious by pouring going on. The shapes of concrete flow line at the bottom of pipe will change along with pouring depth. Order of appearance is overlaying to expanding to pushing up.
