摘要
The paper took Zhouqu Sanyanyu debris flow as a study case, applied the single debris flow risk assessing model; utilized the data of reconnaissance, explorations, and count measures engineering designs; analyzed the risk assessment factors changes at different time points which are before "8.8" disasters, at present, and after count measurements; acquired the parameters of hazards and vulnerability separately; and calculated the risks at these three time points. Finally, discussed the risks assessment results and analyzed the detailed reasons for the risk’s variations at different time points.
