公路施工过程中土石方调配模型优化分析

结合公路建设过程中土石方调配的挖方区、填方区、借方区及弃方区主要性质及特点进行定量分析,建立线性土石方调配优化模型。对公路施工过程中的影响因素进行比较分析,将调配优化模型简化为不同工作区土石方用量与距离运费的综合考虑结果,引入运费系数λ,应用lingo对模型求解,能在工程实践中起到明显的优化作用。

Analysis on Optimization Model for Earth-rock Allocation in the Process of Highway Construction

Depending on the main properties and features of the areas of cutting,filling,borrowing and dumping in earth-rock allocation in the process of highway construction,quantitative analysis was carried out to establish a optimization model for linear earth-rock allocation.Next,through comparison between the affecting factors in this process,this model was simplified into the one from comprehensive consideration of earthwork volume in different working areas and distance freight then with the freight coefficient λ introduced,the model was solved by application of lingo,which may play a significant role of optimization in engineering practice.
