摘要: 目的 针对盾构渣土等工业固废资源化利用的工程问题， 方法 本文通过D-最优混料设计及响应曲面法(Box-behnken设计)研制了一种以盾构渣土为主、工业废料为辅的固废基地质聚合物注浆材料，采用D-最优混料设计筛选盾构渣土、矿渣、钢渣、粉煤灰的固体粉料配比，而后通过响应曲面法分析研究了激发剂模数、浓度、液固比及胶砂比对流动度、28 d抗压、抗折强度的影响规律。结果 D-最优混料设计结果表明：在固体粉料配比为渣土60%、矿渣20%、钢渣15%、粉煤灰5%时，注浆材料具有较好的流动度和力学性能。方差分析结果表明：激发剂浓度对注浆材料流动度影响最显著(P<0.000 1)，其次为激发剂模数、胶砂比、液固比，随着激发剂浓度提高，注浆材料流动度降低，结石体 28 d 强度增加；激发剂模数对结石体 28 d 强度影响最显著，其次为激发剂浓度、胶砂比、液固比，随着激发剂模数提高，注浆材料流动度提高，结石体 28 d 强度降低；建立的流动度、28 d 抗压及抗折强度二次预测模型决定系数R⟡＞0.9，预测值与试验值相对误差＜8%，模型可信度高。结论 本文所研制的固废基地聚合物注浆材料具有较好的流动性和力学性能，研究成果可为实际隧道注浆工程的材料选择提供参考依据，也为盾构渣土等固废资源化利用提供可行途径。

Abstract: Objectives Regarding the engineering issues of resource utilization of industrial solid wastes such as shield muck, Methods a solid - waste - based geopolymer grouting material, with shield muck as the main component and industrial waste as a supplement, was developed through D - optimal mixture design and response surface methodology (Box - Behnken design). The D - optimal mixture design was used to screen the proportions of solid powders, including shield muck, slag, steel slag, and fly ash. Subsequently, the response surface methodology was employed to analyze and investigate the influence laws of activator modulus, concentration, liquid - solid ratio, and binder - sand ratio on flowability, 28 - day compressive strength, and flexural strength. Results The D - optimal mixture design indicated that the grouting material showed favorable flowability and mechanical properties when the solid powder proportion was 60% shield muck, 20% slag, 15% steel slag, and 5% fly ash. Analysis of variance results showed that activator concentration had the most significant effect on the flowability of the grouting material (P < 0.000 1), followed by activator modulus, binder - sand ratio, and liquid - solid ratio. As activator concentration increased, the flowability of the grouting material decreased, while the 28 - day strength of the stone body increased. Activator modulus had the most significant effect on the 28 - day strength of the stone body, followed by activator concentration, binder - sand ratio, and liquid - solid ratio. As activator modulus increased, the flowability of the grouting material improved, but the 28 - day strength of the stone body decreased. The quadratic prediction models established for flowability, 28 - day compressive strength, and flexural strength had coefficient of determination (R⟡ > 0.9, and the relative errors between predicted values and test values were < 8%, indicating that the models were highly reliable. Conclusions The solid - waste - based geopolymer grouting material developed in this study demonstrated good flowability and mechanical properties. The research results provided a reference basis for material selection in actual tunnel grouting projects and offered a feasible approach for the resource utilization of solid wastes such as shield muck.
