摘要
为了合理调配和利用筑路材料,充分贯彻"因地制宜、就地取材"的理念,降低材料投资额,在建立合适数学模型的基础上,将线性规划法用在了路基填料的调配中。通过引入多个松弛变量,采用Matlab编程求解,确定了路基填料的最优调配方案,并比较了其经济性,发现其可以明显降低材料投资额,经济效益显著。
In the construction of road infrastructure, reasonable allocation and use of roadbuilding materials are particularly important to fully implement the idea of ＂local conditions, local materials＂ and reduce material investment. On the basis of establishment of appropriate mathe matical model, the linear programming method was used in allocating subgrade filling material. By introducing more slack variables, the optimal filling allocation plan was decided by means of Matlab programming. Through comparing this plan＇s economy, it is found that this plan signifi cantly decreased material investment. The method was proved practicable for application of linear programming technique to allocate subgrade filling.
