%X 本文基于杭州地铁盾构废弃泥浆固废处理，选用固废再利用矿渣、粉煤灰作为固化剂，生石灰作为碱性激发剂，对废弃泥浆进行固化处理，并对固化产物进行了一系列物理力学特性试验研究。试验结果表明，随着固化剂掺量的参加，固化土的强度明显增长；而当固化剂掺量不变时，矿渣掺量较大时，28 d的无侧限抗压强度较高，水稳系数均大于0.75。试验结果验证了该泥浆固化后可以用作城市道路基底路基材料。<br />
This article is based on the treatment of waste mud and solid waste from shield tunneling in Hangzhou Metro. Solid waste reuse slag and fly ash are selected as solidifying agents, and quicklime is used as an alkaline activator to solidify the waste mud. A series of physical and mechanical properties tests are conducted on the solidified products. The experimental results show that with the addition of a solidifying agent, the strength of the solidified soil increases significantly; When the amount of solidifying agent remains constant and the amount of slag is large, the unconfined compressive strength at 28 days is higher, and the water stability coefficient is greater than 0.75. The experimental results have verified that the solidified slurry can be used as a foundation material for urban roads.
