准确识别滑坡当前所处变形阶段是滑坡预警的重点问题。许多滑坡位移监测曲线并不存在明显的三阶段特征,难以准确识别滑坡目前所处的阶段。基于此,利用形态学思想突破传统斋藤法的限制,建立能够从形态各异的位移曲线中识别滑坡宏观位移阶段的方法;运用该方法从全国4类岩性大区GNSS地表位移监测数据库中识别出1 944条滑坡宏观变形阶段,构建变形阶段大数据样本环境;分析各岩性区内滑坡宏观位移阶段日变形速率分布规律,利用聚类分析构建变形阶段多级预警判据,并对各级预警区间出现的空间概率及持续时间进行讨论。结果表明,4种岩性区内滑坡位移阶段日变形速率均呈现幂函数分布规律,其中日变形速率在10 mm/d以下的数量占比最多;聚类分析表明,各岩性区“无—蓝色—黄色—橙色—红色”五级预警区间内的变形阶段数量均呈现幂函数分布规律。同一预警等级下,岩性1区至岩性4区的变形速率预警阈值呈现递减趋势。变形阶段持续时间分析表明,日速率处于0.08~2.14 mm/d范围的变形阶段持续时间最长,为120.22~160.96 d;日速率处于2 734.18~31 770.00 mm/d范围的变形阶段持续时间最短,为0.004 3~0.020 0 d。分析了大数据环境下我国4类岩性区滑坡宏观位移阶段空间分布规律及预警判据,为今后智能型滑坡位移预警模型构建提供科学依据和指导作用。

Identification of the landslide deformation stage is a key aspect of landslide warning systems. However, many displacement curves lack the obvious characteristics of the three stages, making it challenging to identify the deformation stages of landslides. To overcome the defects of the Saito method, we proposed a method to extract the deformation stages based on a morphology analysis. A total of 1944 deformation stages were identified from the GNSS surface-displacement monitoring database to form a big data environment. Then, we analyzed the spatial distribution of the displacement stages of various lithologic zones in China and used cluster analysis to develop multi-stage warning criteria for deformation stages. The spatial probability and duration of each warning level were also discussed in this study. Analysis results indicated that the power law adequately described the distribution of daily deformation rate for each lithologic region, with daily deformation rates below 10 mm/d accounting for the majority of observations. Cluster analysis revealed that the number of deformation stages within the “none”, “blue”, “yellow”, “orange”, and “red” warning levels also followed the power rule for each lithologic region. It should be noted that the warning threshold of the deformation rate decreased from lithology 1 to lithology 4 at the same warning level. According to the duration analysis of the deformation stage, the longest-lasting daily rate was 0.30~2.14 mm/d with a duration of 120.22~160.96 days; whereas the shortest-lasting daily rate was 2 734.18~31 770.00 mm/d with a duration of 0.004 3~0.020 0 days. In this study, we analyzed the spatial distribution and early-warning criteria of landscape development stages in a big data environment, which could provide a scientific foundation and direction for the development of an intelligent landslide warning model.
