摘要 为系统研究养护龄期对尾砂胶结充填体基本力学性能、应力-应变关系及破坏形态的影响,本工作对处于不同养护龄期下的充填体开展了单轴压缩试验,并基于损伤力学理论建立了考虑养护龄期的分段式损伤本构模型。研究表明:充填体抗压强度和弹性模量随养护龄期的延长呈指数函数递增规律,但在养护后期充填体抗压强度的增长速率随灰砂比的增大而降低;结合充填体应力-应变曲线形态,本工作提出了适用于充填体的单轴受压应力-应变关系表达式,并通过实测值与理论值的对比结果验证了公式的可靠性;当养护龄期超过7 d后,高水泥含量的充填体变形能力随养护龄期的延长呈减小的趋势,而水泥含量低的充填体变形能力与养护龄期呈正相关关系;养护龄期的延长能够对充填体破坏形态产生显著的影响,且实际的影响效果与充填体内部水泥含量具有紧密的相关性。

Abstract: In order to systematically study the influence of curing age on the basic mechanical properties, stress-strain relations and failure modes of cemented tailings backfill, uniaxial compression tests were carried out on the cemented tailings backfill (CTB) specimens at different curing ages. Then, a segmented damage constitutive model considering curing age was established based on damage mechanics theory. The research shows that the compressive strength and elastic modulus of CTB specimens increase exponentially with curing age increasing. And the increasing rate of compressive strength decreases with the cement-sand ratio increasing in late-age curing. According to the stress-strain curve of CTB spe-cimens, the expression of stress-strain relationship under uniaxial compression for CTB specimens was proposed. Moreover, the validity of the formula was verified by comparing the measured value with the theoretical value. When the curing age exceeds 7 d, the deformability of CTB specimens which have the high content of cement is reduced with curing age increasing. However, the deformability of CTB specimens which have the low content of cement has positive relationship with curing age. Therefore, the curing age has a significant effect on the failure mode of CTB specimens, and the actual effect is closely related to the cement content in the backfill.
