Optimization of Filling Unit Division for High Core Rock-Fill Dam Construction

A complete scheme for solving the problems associated with scientific and reasonable division of filling unit for high core rock-fill dam construction was presented. First, based on the analysis of construction characteristics of a high core rock-fill dam, an optimization mathematical model for filling unit division, which considers both the logical relationship of construction procedure and the complex constraints, was developed. Then, two solution methods based on mathematical analysis and construction simulation, respectively, were put forward. Finally, the theories proposed in the paper were applied to a practical project. Results show that the division of filling unit can be analyzed effectively and that scheme optimization can be realized, which provides an effective way for construction organization design and management decision-making.
