Optimization method of earth-rock balance allocation in airport area

The invention relates to the technical field of earthwork construction, and discloses a method for optimizing earth-rock balance allocation in airport field area, comprising the following steps: demarcating a boundary line between a excavation area W and a fill area T on a plan view, and respectively demarcating a plurality of allocation areas in the excavation area W and the fill area T; calculating the earthwork of each allocation area in the excavation area W and the fill area T respectively, and marking them on the plan; calculating an average transportation distance from each allocation area in the excavation area W to each allocation area in the filling area T; determining the deployment plan, including: using the nearest deployment method to determine the initial plan; the initial scheme is checked by the potential method or matrix method to determine whether the total earthwork transportation is the minimum value. If the total earthwork transportation is determined to be the minimum value, the earthwo
