Earthwork Allocation Based on Mathematical Model Algorithm of Linear Programming

土方工程量的计算和合理制定土方调配方案是大型工程建设项目的关键环节,对降低工程建设项目的成本,节省造价有十分重要的意义。传统的土方工程量计算不仅要耗费大量的人力资源与时间,而且计算的土方工程量与实际存在着较大的算量误差。文章主要介绍基于Civil 3D土方工程量算量方法的基本思路以及分析如何借助运筹学线性规划数学模型解决土方工程量的调配问题,并通过工程实例验证数学模型解决土方工程量调配问题的可行性,最终绘制出土方调配方案图,便于施工企业管理者进行土方工程施工决策,制定符合工程实际的土方施工方案。分析表明:运用Civil 3D软件辅助土方工程量计算效率高,结果准确,采用线性规划数学模型解决土方调配问题切实可行。

Earthwork calculation and reasonable formulation of earthwork allocation program are a key part of large-scale construction projects.It is important to reduce and save the cost of construction projects.The traditional earthwork calculation not only consumes lots of human resources and time,but also calculates the amount of earthwork with an actual error.Civil 3D calculation method was introduced,and the problem of earthwork allocation was solved by using liner programming mathematical model of operational research.The results are proved by an example that using reasonable mathematical model to solve the problem of earthwork allocation are feasible.Finally,the earthwork allocation scheme is conveyed by drawing a picture.It is conducive to business managers to make earthwork construction decisions and make earthwork construction plan conforming to engineering practice.The analysis shows that it is feasible to use Civil 3D software to assist earthwork calculation with high efficiency,accurate result and solving the earthwork allocation problem by using linear programming mathematical model.
