Formation mechanism of sudden landslides and prevention and control measures
On the evening of February 20,2020,at 20∶20,a significant landslide occurred at Yangzhai Dapo Group in Guaijiu Village,Baiyi Town,Wudang District,Guiyang City.This study employed data collection,on-site investigation,internal trials,and comprehensive analysis to explore the formation mechanism of the landslide,and to develop emergency prevention strategies.Our findings reveal that the rock soil of the slope comprises a thick,layer-shaped,tattoo-like slice with embedded mud creep rocks,separated by a mud film between layers.The long-term impact of rainfall,surface crack infiltration,and meson penetration into the grooves leads to the entrapment of the rock body,following the formation of a rocky layer.The strategy of"clearing from above,pressing from below,and locking and bundling from the sides"has been proved to be a rapid and effective method to eliminate the risks of geological disasters.The outcomes of this research offer a theoretical and technical framework for addressing similar landslides and formulating prevention and control measures.
