摘　　要：土石方平衡是面板堆石坝施工过程中关系全局的核心问题之一,土石方调配是否合理,直接影响到工程进度、质量、投资等目标的实现。以某面板堆石坝为分析对象,采用系统分析与线性规划的方法,将动态问题静态化,以调配系统的总费用最低为目标,并加入各种实际的约束条件,建立了土石方调配数学模型。在此基础上,使用Lingo软件编程求解该模型,得出最终土石方调配方案。计算结果表明,由于该模型考虑了更多的约束条件,计算结果更加贴近土石方调配的实际情况。The equilibrium of earth-rock material is one of the core issues in the construction of concrete faced rockfill dam, which directly influences realization of engineering schedule, construction quality and investment control. Taking a concrete faced rockfill dam as an example, we adopt the method of system analysis and linear programming to establish a mathematic model of earth-rock allocation. The object of this model is to reach a lowest cost with considering various practical constraint conditions. The final optimized earth-rock allocation scheme of the CFRD is obtained by the model with application of Lingo software. The calculation show that the established model can provide more realistic allocation scheme as more practical constraints conditions is considered.
