Mining of Monitoring Data for Sanmendong Landslide in the Three Gorges Reservoir Area
摘要
Abstract
When traditional association rule mining methods is used to analyze geological hazard monitoring big data in the Three Gorges Reservoir area,multiple scanning of the data is required to mine frequent itemsets,resulting in slow speed and low efficiency.By adopting the FP-Growthalgorithm,and with the Sanmendong landslide as an example,two types of influencing factors,i.e.rainfall and reservoir water level,are selected,and six influencing factors are further subdivided for association rule mining with landslide displacement monitoring data.Eight association rule results are screened out and analyzed to find that there is a significant correlation between landslide displacement and atmospheric rainfall as well as reservoir water level,i.e.the greater the rainfall is,the longer the continuous rainfall time lasts,the greater the landslide displacement is;the greater the change of the reservoir water level per unit time is,the greater the landslide displacement is.The impact of a decrease in reservoir water level on landslide displacement is greater than that of an increase in reservoir water level.The research results indicate that,being more efficient than traditional association rule mining methods andmore suitable for big data analysis,the FP-Growth algorithm can provide implicit,comprehensible and valuable information in big data,and the association rules mined from monitoring data are helpful for landslide deformation analysis.Given the characteristics of multi-source,heterogeneous,and massive geological disaster prevention and control data in the Three Gorges Reservoir area,big data analysis techniques should be more widely applied in geological disaster prevention and control work in the Three Gorges Reservoir area.关键词
