摘要:
为准确描述非饱和细尾矿砂内部含水率的空间分布规律，采用解析方法求解了非饱和尾矿砂的二维Richards方程，探讨了解析求解过程中方程和求解区域简化的思路，介绍了非饱和细尾矿砂含水率空间分布的实验结果，采用混沌粒子群优化算法计算了求解过程中引入的常数。研究结果表明：解析解具有无穷级数的形式，且级数的系数具有很好的收敛性，非饱和细尾矿砂含水率在水平和竖直方向上的分布均近似服从指数函数，混沌粒子群优化算法的误差收敛性明显，利用解析模型得到的各点含水率计算值与实验测量值均符合的比较好。所得解析公式能够很好地描述非饱和细尾矿砂内部含水率的空间分布规律。
Abstract:
To describe the spatial distribution laws of internal water content in the unsaturated fine tailing sand accurately, the twodimensional Richards equation of unsaturated tailing sand was solved by using the analytical method, and the thoughts about the simplification of equation and solving area in process of analytical solving were discussed. The experimental results of spatial distribution of water content in the unsaturated fine tailing sand were introduced, and the constant parameters conducted into the solving process were calculated by using the chaos particle swarm optimization algorithm. The results showed that the analytical solution was in the form of infinite series, and the coefficient of series had good convergence. The distribution of water content in the unsaturated fine tailing sand in both vertical and horizontal directions approximately obeyed the exponential function. The error convergence of chaos particle swarm optimization algorithm was obvious, and the calculation results of water content in each point by the analytical model fitted well with those obtained by experimental measurement. The obtained analytical equations could describe the spatial distribution laws of internal water content in the unsaturated fine tailing sand well.
