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，开展基于响应曲面法的固废基地聚物注浆材料优化研究。  方法 通过D -最优混料设计和响应曲面法研制一种以盾构渣土为主、工业废料为辅的固废基地聚合物注浆材料，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 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，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抗压、抗折强度增加；激发剂模数对结石体28 d抗压、抗折强度影响最显著，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抗压、抗折强度降低；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R²>0.9，预测值与试验值相对误差小于8%，模型可信度高。  结论 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 To address the engineering challenge of resource utilization of industrial solid wastes， particularly shield muck， and to optimize a solid waste-based geopolymer grouting material using response surface methodology.  Methods A solid waste-based geopolymer grouting material， with shield muck as the primary component and other industrial wastes as supplementary materials， was developed through D-optimal mixture design and response surface methodology. The D -optimal mixture design was employed to determine the optimal proportions of solid powders， including shield muck， slag， steel slag， and fly ash. Subsequently， response surface methodology was used to investigate the effects of activator modulus， activator concentration， liquid-to-solid ratio， and binder-to-sand ratio on flowability， 28-day compressive strength， and flexural strength of the hardened grout.  Results Results showed that the grouting material exhibited favorable flowability and mechanical properties when the solid powder proportion consisted of 60% shield muck， 20% slag， 15% steel slag， and 5% fly ash. Analysis of variance showed that activator concentration had the most significant effect on flowability， followed by activator modulus， binder-to-sand ratio， and liquid-to-solid ratio. As activator concentration increased， the flowability of the grouting material decreased， whereas the 28-day compressive and flexural strengths of the hardened grout increased. Activator modulus had the most significant effect on the 28-day compressive and flexural strengths of the hardened grout， followed by activator concentration，  binder-to-sand ratio， and liquid-to-solid ratio. As activator modulus increased， flowability improved， whereas the 28-day compressive and flexural strengths decreased. The quadratic prediction models established for flowability， 28-day compressive strength， and flexural strength exhibited coefficients of determination greater than 0.9， and the relative errors between predicted and experimental values were less than 8%， indicating high model reliability.  Conclusions The developed solid waste-based geopolymer grouting material exhibits excellent flowability and mechanical properties. These findings provide technical guidance for material selection in tunnel grouting projects and offer a feasible approach for the resource utilization of shield muck and other industrial solid wastes.
