摘要： 模袋体在细粒尾矿库治理与加固工程中有广阔应用前景。为探究细粒尾矿充填模袋体在固结过程中的剪切特性，开展了场地固结试验研究。选取 2 种尾矿和 4 种不同规格编织型土工织物制备模袋体，并通过直剪试验分析了不同固结时间条件下尾矿干密度、尾矿及模袋体的抗剪强度演化规律，揭示尾矿性质、土工织物参数及固结时间对模袋体力学性能的影响机制。结果表明：随着固结时间延长，尾矿干密度呈二次函数增长并逐渐趋于稳定，固结 40 d 后干密度提升 30% 以上。土工织物的渗透性能和力学性能对固结效果及抗剪强度具有重要影响，渗透系数越大，尾矿固结程度越高；土工织物抗拉强度越大，模袋体强度提升越显著。相比纯尾矿，模袋体的黏聚力提高 4～7倍，而摩擦角提升幅度较小。尾矿干密度与抗剪强度参数间存在显著的二次函数关系，可基于易测的干密度参数预测强度指标。研究成果可为尾矿库工程中模袋体稳定性分析及土工织物选型提供理论依据和工程参考。

Abstract: Geotextile tubes have broad application prospects in the treatment and reinforcement of fine-grained tailings dams. To investigate the shear characteristics of geotextile tubes filled with fine�grained tailings during the consolidation process，field-scale consolidation tests were conducted. Two types of tailings and four types of woven geotextiles with different specifications were selected to prepare geotextile tubes. Direct shear tests were performed to analyze the evolution of tailings dry density as well as the shear strength of both tailings and geotextile tubes under different consolidation durations. The influ⁃ ence mechanisms of tailings properties，geotextile parameters，and consolidation time on the mechanical behavior of geotextile tubes were revealed. The results show that with increasing consolidation time，the dry density of tailings increases following a quadratic function and gradually stabilizes，with an increase of more than 30% after 40 days of consolidation. The permeability and mechanical properties of geotextiles have significant effects on the consolidation efficiency and shear strength. A higher permeability coefficient leads to a higher degree of consolidation，while greater tensile strength of geotextiles results in more pro⁃ nounced strength improvement of the geotextile tubes. Compared with pure tailings，the cohesion of geotex⁃ tile tubes increases by 4~7 times，whereas the increase in internal friction angle is relatively limited. A sig⁃ nificant quadratic relationship exists between tailings dry density and shear strength parameters，allowing the prediction of strength indicators based on easily measurable dry density parameters. The findings pro⁃ vide a theoretical basis and engineering reference for the stability analysis of geotextile tubes and the selec⁃ tion of geotextiles in tailings dam engineering.
