摘　　要：土方工程施工优化土方调配可以达到缩短工期和降低成本的目的,土方最优调配方案的求解一直是土木工程研究的焦点之一。土方调配问题也是土地开发和工程建设中的重要环节,其合理调配方案对于工程进度和成本控制具有重要影响。数学层面土方调配是典型的优化问题,本研究基于优化问题的非线性规划模型,将土方调配问题作为非线性规划问题求解,以土方调配问题的优化目标和约束条件为基础,建立土方运输成本与土方量的非线性函数,提出土方调配的最优求解算法。利用MATLAB软件解决土方最优调配方案求解问题,并结合具体案例进行分析,验证了非线性规划模型的有效性和可行性。Optimizing earthwork allocation in earthwork construction can achieve the goal of shortening the construction period and reducing costs.The solution of the optimal earthwork allocation scheme has always been one of the focuses of civil engineering research.The issue of earthwork allocation is also an important link in land development and engineering construction,and its reasonable allocation plan has a significant impact on the progress and cost of the project.In mathematics,earthwork allocation is a typical optimization problem.Based on the nonlinear programming model of the optimization problem,this paper solves the earthwork allocation problem as a nonlinear programming problem.Based on the optimization objectives and constraints of the earthwork allocation problem,a nonlinear function of earthwork transportation cost and earthwork volume is established,and an optimal solution algorithm for earthwork allocation is proposed.Using MATLAB software to solve the problem of optimal earthwork allocation scheme,and combining with specific cases for analysis,the effectiveness and feasibility of the nonlinear programming model are verified.
