Risk Assessment of Geological Hazards in Important Construction Engi-neering Sites in Northern Shaanxi Region
[Purposes]The risk assessment of large-scale site construction projects in northern Shaanxi province is currently conducted considering the combined impact of various factors,including geological hazards such as collapse and landslide,as well as overlying mineral resources.[Methods]This paper presents the methods and contents of risk assessment work based on a large photovoltaic power genera-tion construction project in Fugu County,describing common influencing factors,causes,and prevention measures for typical geological disasters in the area.[Findings]It is preliminarily found that the land-slide and collapse disasters in the overburden area are affected by topography,lithology,rainfall and hu-man factors.The influencing factors of mining collapse are earthquake,groundwater level change and mining activities,which are mainly mining activities in this area.[Conclusions]Considering these fac-tors and the project's specific characteristics,avoidance measures for geological disasters like landslides and collapses should be implemented while long-term monitoring measures are taken for cave-ins.The research results have certain practical significance for guiding the risk assessment of engineering con-struction in this area.
