本文在研究广元市金洞乡Ⅱ号滑坡位移特征基础 ,认为该滑坡正处于开放的、复杂的非线动力学系统中。在滑坡系统诸要素中 ,宝珠寺库水位的升降已成为系统演化的控制力量。坡体位移是系统演化的主要状态变量 ,但北部坡体、南部坡体与中部坡体之间的滑动变形具较强的独立性 ,单一的位移序列不能较好的反映滑坡的演化特征。因此 ,文中以两列独立的位序列为状态变量 ,结合控制变量建立了滑坡系统演化的非线性动力学模型 ,并从现有的变形监测粢资料进行滑坡系统的非线性动力学反演和稳定学反演和稳定性评价。
This paper studies the displacement characteristics of the landslide No.2 in Jindong Township, Guangyuan, which is considered as an open and complicated nonlinear dynamic system. Among the various elements of the landslide system, the water level rise and fall of the Baozhusi reservoir has become the controlling force of the system evolution. The displacement of the slope body is the main state variable of the system evolution. However, the sliding deformation between the northern slope body, the southern slope body and the central slope body is strongly independent. The single displacement sequence can not reflect the evolution characteristics of the landslide well. Therefore, in this paper, a nonlinear dynamic model of landslide system evolution is established based on two independent bit sequences as state variables and the control variables. Based on the existing deformation monitoring data, the nonlinear dynamic inversion and stability of the landslide system Inversion and Stability Evaluation.
