A discussion on the assessment of geological hazard risks in key survey areas(1∶10000):An example from the key survey area in Qijing Village,Shitai,Anhui
The geological hazard risk assessment in key survey areas is focused on the survey and assessment of the slope unit.Compared with that in general survey areas,it has clear assessment subject,distinct gradation and relevant accuracy.The working method is as following:firstly,classify different slope units based on field observation and engineering geological surveying and mapping,and then quantitatively describe the failure probability and dangerousness of a slope unit under different working conditions,finally,conduct risk assessment based on the dangerousness of the slope and the characteristics of the affected objects.
