尾矿砂中掺加具有大量粘性颗粒的土,会明显改善尾矿砂的塑像,进而能将压实强度明显提高而进行路基的填筑。在确定每一种土的物理性质并进行对比选择后,加入15%的水泥CBR值迅速增加即可达到填筑路基的要求。通过多种室内试验,尾矿砂掺入粘性土的路基填料既能达到压实的目的,又不会引起其他不利因素。
Tailings sand mixed with a large number of sticky particles of soil, will significantly improve the statue of tailings sand, which can significantly improve the compaction strength of the roadbed filling. After determining the physical properties of each type of soil and making a comparative choice, adding 15% of the CBR value of the cement quickly increases to meet the requirements for roadbed filling. Through a variety of laboratory tests, the roadbed filler of tailing sand mixed with clay can achieve the purpose of compaction without causing other unfavorable factors.
