烧结法赤泥的强度演化规律

筑坝堆存是现在处理赤泥的主要方式,为了堆场安全继续向上堆载,对烧结法赤泥强度的演变规律进行了研究。通过对比不同深度处赤泥的抗剪强度,表明赤泥强度的形成与堆载时间没有必然的联系;再通过对新进场的赤泥进行强度追踪,得到赤泥强度形成过程中抗剪强度与滤水固结时间的关系曲线,从时间因素上为赤泥的安全堆载提供一个理论依据。

Research on strength evolution law of red mud from sintering process

Dam stockpiling is the main method to deal with red mud recently,this paper discusses the evolution rule of the strength of red mud from sintering process for the security of surcharge loading continuously.By comparing the shear strength at different depths of red mud,we find that the formation of the strength of red mud has no necessary relationship with heap load time.Then through the strength tracking of the new red mud,the relationship curve of the formation of shear strength and drainage consolidation time is obtained,which provides a theoretical basis for the safety of surcharge loading by the time factor.
