摘要
为深入研究重庆市某干线公路顺层滑坡的垮塌机理,该文采用非线性粘弹塑性流变模型对该干线公路某顺层滑坡进行了数值模拟研究,深入分析了结构面流变作用下滑坡体位移、应力以及安全系数等的变化特征。结果表明,结构面流变特性是该滑坡发生的主要原因,非线性粘弹塑流变模型可很好地分析带有软弱结构面的顺层滑坡稳定性问题,研究成果可为同类滑坡的稳定性及失稳机理研究提供借鉴依据。
Abstract： To deeply study the collapse mechanism of the＇bedded slope of an arterial road in Chongqing, nonlinear viscoelastic plastic rheologi- cal model is adopted to do numerical simulation to study the bedding landslide of the arterial road and deeply analyze the change characteristics of land- slide displacement, stress and safety factor under structural surface rheology. The results show that rheological properties of structural surface is the main cause of landslide and nonlinear viscoelastic plastic rheological model can excellently analyze the stability problems of bedded slope with weak structural plane. The study can offer some references for similar study on stability and instability mechanism of landslide,
