As the main machine for concrete pouring of high arch dam, improving the utilization rate of the cable machine is of great practical significance to speed up the progress of the project, shorten the construction period, reduce the cost and ensure the quality of the project. Based on the deep analysis of the conditions and interferences of double-cages combined pouring of cable machine, the spare-pouring capacity of cable machine is fully exploited, and the simulation optimization model of double-cages combined pouring of high arch dam cable machine is established by taking the cable machine as the basic decision unit. Optimization model takes balancing the construction intensity, improving the utilization rate of cable machine and speeding up the construction schedule as the goal. The scheme is determined through optimization of the cable machine scheduling. The research results are applied to the construction of a certain dam concrete pouring, which has important theoretical significance for guiding the concrete construction and optimizing the pouring scheme of high arch dam.
