摘要:利用传统CAD图纸进行土方工程量计算不仅需要耗费大量的人力物力，而且计算的土方量与实际存在较大的差别；在实际施工中项目管理人员大多是根据实际工程经验制定土方调配方案，该方法不能够满足大型复杂项目的土方调配。因此在准确计算土方量的基础上满足挖填平衡、全局最优的原则建立土方调配模型，制定土方调配方案至关重要。本文依托某机场项目为其提供最优化的土方调配方案，主要介绍基于三维实景和BIM模型土方工程量准确算量的基本思路和方法，并在运筹学线性规划数学模型的基础上利用MATLAB计算土方调配方案，通过某机场的工程实例验证该方法的可行性。
Abstract: 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.
