摘要
1920年的海原大地震是我国历史上最大的地震之一,地震释放出巨大的能量,并诱发大量山体滑坡.选取其中较为典型的黄土滑坡群开展调查,通过地质测绘、测量、现场勘探与数据分析等综合手段,对连拱状后壁滑坡群的成因机制进行了分析研究,并将此类滑坡的运动特征分解为4个阶段进行分析,总结出此类滑坡的一般发育规律和运动特征.
Haiyuan earthquake was one of the largest earthquakes with a magnitude of 8.5 in the history of China in 1920.It released a huge amount of energy,and also induced landslides in great quantities.This paper was to select some of the typical loess landslide group to carry out the research work.Through the engineering geological surveying and mapping,engineering surveying,engineering drilling,data analysis and other comprehensive means,the formation mechanism of the back-to-back wall landslide group were analyzed,and the movement characteristics of this kind of landslide were classified into four stages.Finally,the paper summarized the general development law and movement characteristics of this kind of landslide.
