| 摘 要： | 本研究的目的是建立一种简单实用的上游式尾矿坝非饱和带滞水曲线的数学模型。研究方法采用拟合法。在揭示了硬岩尾矿砂的沉积距离与含水率、孔隙比等之间关系的基础上,建立了一种arctanx的函数,用来表征含水率与基质吸力的关系。将本模型应用于降雨入渗条件下饱和-非饱和渗流场分析,结果表明,数学模型与实验数据,具有明显的一致性。研究表明:该数学模型函数简单,适用于上游式尾矿坝。

| Abstract: | The purpose of this research is to establish a simple and practical mathematical model for the water retention curve in unsaturated section of upstream embankment constructed tailings dam .The fitting method is adopted in the article .Through discovering the relationships between sediment distance and the volumetric water content , the void ratio etc, a function of arctg(x) is adopted to express the relation between the volumetric water content () and the suction (). It proves that the mathematical model and the experiment data have obvious consistency, when this model is applied to analyze the saturated-unsaturated seepage field under the condition of rainfall infiltration. It can conclude that the mathematics model is a simple function, and it can be used in the upstream embankment constructed tailings dam. |
