Using traditional CAD drawings for earthwork calculation not only requires a lot of manpower and material resources, the calculated earthwork amount is quite different from the actual. In the actual construction, most project managers make earthwork allocation plans based on actual engineering experience which cann′t meet the earthwork deployment of large and complex projects. Therefore, it is very important to establish an earthwork allocation model based on the accurate calculation of the earthwork volume to satisfy the principle of digging and filling balance and global optimization, and to formulate an earthwork allocation plan. This article relies on an airport project to provide the most optimized earthwork allocation plan. It mainly introduces the basic ideas and methods for calculating the amount of earthwork based on the three-dimensional real scene and BIM model, and uses MATLAB to calculate the earthwork based on the mathematical model of operations research linear programming. The deployment plan is used to verify the feasibility of the method through an engineering example at an airport.
