Dam concrete construction is a typical discrete event dynamic system (DEDS) .The interaction within system is so complex that it is difficult to figure out with a mathematical model. This paper introduces the simulation model of dam concrete construction process based on timed Petri nets, which are fit to describe transformation of system form and state. A case study shows that the modelling system using timed Petri nets is feasible in the dam concrete construction process. the process simulation is easy to be understood and analyzed.
