Modeling of Earthwork Dynamic Allocation for Rock-Fill Dams

By analyzing feeding sources and material accepted fields involved in the earthwork allocation for rock-fill dam, a dynamic model of earthwork allocation is set up by incorporating dynamic programming. Dividing filling and excavation process into n steps, functions of allocation costs during each period is defined according to equation of state transitions, on the basis of which the optimization function is formed. Then the sequential method is employed to get the optimized solution. Finally a practical case is studied for application of this model.
