| 摘 要： | 滑坡是水库库区主要地质灾害类型之一,开展水库滑坡成因机制研究具有重要理论意义和工程应用价值.利用WebofScience(WoS)数据库和VOSviewer文献计量工具对1999-2018年已发表的969篇以水库滑坡为主题的相关论文进行研究趋势分析.文献计量分析表明三峡库区滑坡稳定性和变形研究是未来水库滑坡成因机制研究主要趋势.从库水对滑坡的宏观力学作用方式、库水作用下岩土体渗流应力耦合机理和库水对岩土体劣化作用过程等方面,对国内外水库滑坡成因机制研究的主要成果与进展进行了综述.综合现有的研究成果指出水库滑坡在精细化地质建模、岩土体多场耦合特征参数获取和岸坡长期演化评价等方面尚存在不足.基于上述问题,提出水库滑坡成因机制研究应以多场信息监测为重要手段,立足多学科交叉,采用大数据融合与挖掘和人工智能技术等解决水库滑坡长期演化趋势难题.考虑水库滑坡所处地质环境的复杂性,建议未来应在水库滑坡立体精细地质建模、多场关联监测、地质结构多场多尺度演变过程、基于监测数据大数据分析的滑坡预警阈值确定和原位试验综合平台构建等方面进一步深入研究.

| Abstract: | Reservoir landslide is one of the main type geohazards in the reservoir area.It is of great theoretical significance and engineering application value to carry out formation mechanism research of reservoir landslides.To figure out the research trends, 969 papers about reservoir landslides published from 1999 to 2018 in Web of Science database were searched and conducted a statistically analysis with the bibliometric tool VOSviewer.The results show that landslides stability and deformation will be the heated issue in the Three Gorges Reservoir Area in future related reservoir landslides research.In this paper, the main achievements and progress of reservoir landslide mechanism research at home and abroad are summarized in terms of the macroscopic mechanical action mode of reservoir water on landslide, the seepage stress coupling mechanism of rock-soil mass under the action of reservoir water and the deterioration process of rock-soil mass under the action of reservoir water.Analyzing the existing research results, there are some problems in the fine modeling of reservoir landslide, the multi-field acquisition of characteristic parameters of rock and soil, the evaluation of long-term evolution of bank slopes, etc.To deal with the problem of previous literature reviews and realizing long-term stability of reservoir landslides, the research system of reservoir landslides should be founded that multi-field monitoring is regarded as the key manner and the strategy of combining multidisciplinary intersection with artificial intelligence and big data analysis is also considered as the crucial technology.Considered the complexity of geological environment of reservoir landslides, the future research directions of reservoir landslides are proposed to perform related research on reservoir landslides.Breakthrough achievements will be made if researchers focus on that fine geological model, reservoir landslide multi-field relevance monitoring technology, the multi-scale process of the reservoir landslide geological structure evolution, the determination of reservoir landslide warning threshold with monitoring data of big data analysis and the construction of reservoir landslide in situ testing ground platform. |
