On August 8, 2021, Quxian County was hit by a heavy rainstorm, causing 38 new disasters and aggravating 109 existing disasters to varying degrees. Based on field survey , this paper studies the characteristics of disasters caused by heavy rainstorms and the relationship between the hazard including and geological conditions and disaster distribution. The results show that: the new disaster points caused by the heavy rain in Quxian County are mainly soil landslides, accounting for 94.7%; the regional slope structure has the highest impact on the disaster occurrence; Soil landslides occurred in 300～325 mm accumulative rainfall range, up to 27 places; There are 23 disaster points with serious signs of aggravation of deformation, which are distributed in the range of accumulative rainfall of 337～348 mm; It can provide a scientific basis for the county’s geological disaster prevention and control zoning and flood season geological disaster prevention, and can provide a reference for disaster prevention and mitigation of geological disasters in similar areas with heavy rainstorms. |
