| Abstract: |
| Comprehensive optimization of high earth-rockfill dam construction schedule is a complex nonlinear
multi-objective decision-making problem, which needs not only to consider the resources allocation and production
effectiveness, but also to take into account the influence of compaction quality and dam safety on dam construction
schedule. On the basis of quantitatively analyzing the relationship among compaction quality, dam safety and
construction schedule, a comprehensive optimum model of the construction schedule coupling compaction quality
and dam safety was established. To overcome the limitations of some traditional optimal methods, a genetic harmony
search algorithm for the model was presented to achieve the best arrangement of the high earth-rockfill dam
construction schedule with consideration of compaction quality and dam safety. Finally, a case study was given to
prove the feasibility of the method mentioned above. It is shown that the method provided by the paper may be a
new approach to optimizing and real-time controlling of high earth-rockfill dam construction schedules. |
