以小洞槽边坡为例，对反倾边坡倾倒的时空特征进行了综合分析。首先，在野外勘察和工程地质资料解释的基础上，对倾倒变形进行了空间分区分析。然后，结合地表位移监测数据，分析了边坡不同区域倾倒变形的时域变化规律。最后，利用离散点地表监测数据的距离加权反插值，构造倾倒位移演化等时线。研究结果表明：（1）坡体后部的位移以垂直变形为主，坡体前部的位移以水平变形为主，水平变形控制着岸坡的整体变形;（2）坡体变形的整体演化受坡体中心地带的控制。特别是边坡整体变形滞后于中心区域，该带状区域的位移可能引发岸坡整体位移。由此推断，条带区是边坡倾倒变形的锁定段。
In this paper, a comprehensive analysis of spatiotemporal characteristics of reverse-dip slope toppling is conducted by taking the Xiaodongcao slope as an example. First, a spatial partitioning analysis of toppling deformation is performed based on the field reconnaissance and interpretation of engineering geological data. Then, the variations of toppling deformation in time domain are analyzed for different areas of the slope with monitored data of surface displacement. Finally, the isochrones of toppling displacement evolution are constructed by using inverse distance weighted interpolation of surface monitoring data at discrete locations. The results presented in the study have shown that: (1) the displacement at the rear of the slope is dominated by vertical deformation, whereas the horizontal deformation is predominant at the slope front which also controls the overall deformation of the bank slope; (2) the overall evolution of slope deformation is dominated by the strip area at the center of the slope. In particular, the overall deformation of the slope lags behind the central region, and the displacement in this strip area could trigger an overall displacement of the bank slope. It is thus inferred that the stripe area serves as the locked segment for the toppling deformation of the slope.
