摘要为研究断层破碎带岩体突水灾变规律，开展破碎带岩体蠕变‐冲蚀耦合力学特性的试验研究。发明并创新了渗透缸筒内壁周围注水与轴向应力加载的试验方法，突破了渗透作用下细小物质由四周向中心径向迁移的核心问题，开展多因素条件下的破碎带岩体流‐固耦合试验，获得变质量突水过程中破碎带岩体的变形与渗流特征。试验结果表明，变质量突水过程可以分为初始期、冲蚀主控期、蠕变主控期3个阶段；其中，冲蚀主控期是决定变质量突水灾害萌发的关键时期，而蠕变主控期产生的岩体变形将导致围岩失稳灾害。在轴压和内径尺寸较大、水压和胶结强度较小的试样中，可观察到更加显著的蠕变效应；水压和内径尺寸较大、轴压和胶结强度较小的试样中，可观察到更加显著的冲蚀效应。轴压和胶结强度为破碎带岩体蠕变的主控因素；而轴压、水压、胶结强度与内径尺寸四者均对岩体冲蚀产生了较大影响。

Abstract：In order to study the evolution law of water inrush disasters in fault fracture zones，an experimental research on creep-erosion coupling mechanical characteristics of fault fracture rock masses was conducted in this paper. A novel test method，for infecting water around the inner of the seepage cylinder and loading in the axial direction，was invented and innovated，by which the core issue of radial migration of fine rock particles from the surrounding to the center under the action of seepage was broken through. A series of fluid-structure coupling tests of fault fracture rocks under multi-factor conditions were carried out，and the deformation and seepage characteristics of fault fracture rocks during variable-mass water inrush were obtained. The test results show that the variable-mass water inrush process can be divided into three stages，i.e.，the initial stage，the erosion period and the creep period. Among them，the erosion period is the key that determines the germination of variable-mass water inrush disasters，and during the creep period，the large deformation will induce the instability disaster of surrounding rocks. More significant creep effects can be observed in the samples with larger axial stress，larger bore diameter，lower water pressure and lower cementing strength. More obvious erosion effects can be observed in the samples with larger water pressure，larger inner diameter，smaller axial stress and smaller cementing strength. Among influencing factors，the axial stress and the cementing strength are the main controlling factors for the creep behavior of fault rocks，while the axial stress，the water pressure，the cementing strength and the bore diameter all have a great effect on the erosion behavior.
