Stability Analysis and Treatment Plan Research on K2+240 Landslide Section of Yongchang Highway
After the collapse of K2+240 section of Yongchang Highway,the roadbed,pavement,and mountains sank as a whole,causing traffic interruption.The reason for collapse is that under the influence of reservoir water storage,the strength of rock and soil in the lower slope of highway decreases,causing the stability of slope to be destroyed.During the continuous decline of reservoir water level,due to the poor permeability of clay,schist,and other materials in the slope,the groundwater in the slope cannot be discharged in a timely manner,and the deformation of slope further develops.Based on the causes of slope collapse,a design proposal is proposed to use anti slip piles and retaining plates for support,and the implementation effect is significant.
