In this paper, DELMIA software was used to apply construction simulation to RCC arch dam to visualize and digitalize the construction process. The concrete transportation and pouring of roller compacted concrete arch dam were mainly studied. Using this simulation technology to simulate the construction process, it was easier to change the parameters and modify the scheme. It could optimize the mechanical configuration, construction technology parameters and construction scheme. The DPM module of DELMIA made full use of the three-dimensional data of the “digital prototype” to realize 3D scheme planning based on the three-dimensional, and conducted the three-dimensional visualization simulation and verification of the project construction process, resource allocation and node control. Visual simulation creation methods enabled the visualization of simulation modeling, model processing, simulation processes and simulation results. The QUEST of DELMIA module used the discrete event dynamic system network model to dynamically simulate and combined the queuing theory in the system engineering with the actual logic constraints to obtain simulation results that were basically consistent with the actual. The theoretical method and application of simulation and optimization of high RCC arch dam construction process based on DELMIA were studied. Through the DPM study of DELMIA, the dynamic visualization simulation of the construction process of RCC arch dam was realized. Through the safety simulation of personnel construction, the design of construction auxiliary facilities was promoted, the safety of personnel operation was guaranteed and the connection and construction of construction plan and three-dimensional were realized. Using the QUEST of DELMIA, the queuing network simulation model of concrete construction transportation system was established and the queuing problem of concrete transportation was solved by discrete analysis technology.
