| 摘 要： | 对于复杂地形的尾矿坝,由于二维模型不能充分反映复杂多变的渗流域,也不能考虑到三个方向渗流因素同时作用的影响,从而无法体现真正的渗流场.通过建立三维渗流数学模型,并考虑复杂断面概化和地形的简化,对实际工程进行了数值计算,其结果与试验结果吻合较好.结果表明,对复杂地形的尾矿坝渗流分析时必须采用三维模型,三维数值计算中对复杂地形进行适当的简化和概化对结果的影响较小,可以满足精度要求,因此大大减小了计算的复杂程度和难度.

| Abstract: | For the complex topographical tailings dam, neither the complicated and changeable seepage field nor the action of three direction seepage factors at the same time can be fully reflected in the two-dimension model; as a result the real seepage field cannot be acquired. A three-dimension mathematical model is set up; and both section and terrain are simplified. An example is giyen; and the result is compared with that of the test .The better identical result indicated that the three-dimension model must be adopted in the seepage analysis of the complicated topographical tailings dam; and the appropriate predigestion can satisfy the precision and reduce the complicity and difficulty. |
