摘　　要： 为了解决含硫化物矿山中AMD蚀化对岩石力学性质的影响问题,采用概率论和连续损伤理论相结合的方法,研究了AMD蚀化下岩石的损伤统计本构模型,并引用试验资料对模型进行了验证。结果表明:模型理论曲线与试验曲线具有较高的吻合度,所建模型能够较好地反映受腐蚀岩石在三向压力作用下的应力—应变全过程和岩石强度变化特征,说明本文所建立的模型是合理的。该成果对岩体工程具有一定的参考价值和指导意义。 In order to solve the problem of the influence of AMD corrosion on rock mechanics properties in sulfide mines,the damage statistical constitutive model of corroded rock is studied by using probability theory and continuous damage theory.Then the constitutive model was verified by test data of triaxial experiment.The result indicates that the model theoretical curves coincide with the test curve to great extent has high alignment and the proposed constitutive model can reflect the relationship between stress and strain of rock subjected to acid attack and changes characteristics of rock strength,which shows that the proposed constitutive model is rational and feasible.The result has important guiding sense to the rock mass engineering.
