通过分析糯扎渡心墙堆石坝土石方填筑和开挖工程之间的料源平衡和进度协调的关系，采用线性规划方法 ，结合施工中的实际因素，建立土石方调配优化数学模型。通过实际运用，达到了节约资源、节省费用、合理快速施工的目的。

In order to balance the relation between earth-rock works excavation and earth-rock filling in the construction process of the Nuozhadu Core Rockfill Dam, an optimized mathematical model was established by adopting the linear programming method and in combination with the practical factors during construction. Through the numerical simulation of construction process, the aims of source economizing, cost saving and rationally quick construction attained.
