摘要:
 在滑坡传统条块法分析的基础上，应用部分强度折减法及理想弹塑性模型，用推广的条块法模拟边坡的渐进破坏过程，提出临界状态条块的决定方法，使边坡的传统条块稳定分析与变形紧密相关。在边坡临界状态逐步移动过程中滑体整体曲线表现出摩阻力随之减小，剩余推力和驱动下滑力随之增大，当所划分的最后条块达到临界状态，则边坡发生破坏。以巴东青干河桥头边坡为例，以不平衡推力数值条分法理想弹塑性模型揭示边坡的渐进破坏过程中各物理力学参量的演化特征，对边坡全过程渐进破坏中的点、面进行多参量评价分析。研究结果表明：数值模拟的条块分析法较好地描述巴东青干河桥头边坡的渐进破坏过程，并为边坡检测以及防范提供支撑。
Abstract:
 The analysis and prevention of landslide failure process is a hot research topic nowadays. On the basis of the traditional strip method analysis of landslides, the partial strength reduction method and the ideal elastoplastic model are used to simulate the progressive failure process of the slope with the popular strip method, and the critical state strip determination method is proposed to make the slope. Traditional bar stability analysis is closely related to deformation. During the gradual movement of the critical state of the slope, the overall curve of the sliding body shows that the friction resistance decreases, and the remaining thrust and driving sliding force increase accordingly. When the last divided block reaches the critical state, the slope is destroyed. Taking the slope at the bridgehead of Badong Qinggan River as an example, the ideal elastoplastic model of the unbalanced thrust numerical slice method is used to reveal the evolution characteristics of various physical and mechanical parameters in the progressive failure process of the slope, and to determine the point in the progressive failure of the slope in the whole process by performing multi-parameter evaluation and analysis. The research results show that the block analysis method of numerical simulation can better describe the progressive failure process of the slope at the head of the Qinggan River in Badong, and provide support for slope detection and prevention.
