【摘要】 在万州侏罗纪红层中,连续分布多层产状稳定、厚度较大的软弱夹层,容易成为岩质滑坡的滑动面。万州区近水平滑坡的成因一直存在争议,为了从力学角度阐明万州区滑坡的成因机制,对万州区红层软弱夹层进行了排水蠕变试验,以研究软弱夹层的流变性能。采用Singh-Mitchell模型描述了软弱夹层的蠕变特性,并对模型中的参数进行了探讨,为从力学机制研究万州区近水平滑坡的成因机制提供模型和参数。更多还原

【Abstract】 Several stable,continuous and thick incompetent beds exist in Jurassic red strata in Wanzhou,which become sliding surfaces of rock landslides easily. The cause of the approximate level red beds landslides in Wanzhou is debatable. In order to clarify that base on mechanics,creep tests have been carried out to study the rheological property of incompetent beds,and Singh-Mitchell model is used to describe the creep character of the incompetent beds. The parameters of Singh-Mitchell model are discussed,which provides the model and parameter for further research.更多还原
