摘要
本文介绍了齐大山铁矿尾矿筑坝工艺、模型试验及坝体稳定性分析的主要研究成果,将上游法的堆筑程序改为库内上下游部位交替排放坝体交替上升的筑坝工艺,增加库容521万m^32。考虑放矿水影响,坝体在7度地震是稳定的,8度地震,坝体局部地段可能失稳,须要考虑防震措施。
This paper presents the important advances in technique for construction of tailing dams, model tests and in stability analysis at Qi Dashan Iron Mine. By using the upstream method of alternative discharge and rise in the front and back of the impoundment, the storage capacity for the dam is increased by 5.21 million m^3. The tailing dam is stable against 7° earthquake and may be locally unstable against 8°, and hence a earthquake-proof construction is necessary.
