| 摘 要： | 采用龙都尾矿库内的细粒尾矿作为试验材料,以该尾矿库的设计尾矿坝为原形堆积尾矿坝体模型,进行细粒尾矿堆坝加筋加固模型试验。通过模型试验,检验了细粒尾矿堆积的尾矿堆坝加筋加固的作用效果,获得了加筋尾矿坝体与不加筋尾矿坝体的不同破坏模式,在细粒尾矿堆坝的稳定性研究以及将加筋材料应用于尾矿坝的加固方面作了一些新的探索。

| Abstract: | Taking the materials of the fine tailings from Longdu tailings pond as a case study,the model,based on the design tailings dam of Longdu tailings pond,was performed to study the stability of fine grained tailings dam in two situations,with and without geo-grid reinforcement. The effects of geo-grid reinforcement were verified. At same time,the failure patterns of dam with and without reinforcement were presented,where the former slide surface is found to be rotational and the later to be wedge. The results provide a new approach in the stability research on fine-grained tailings dam and the application of geo-grid. |
