摘要
Abstract
This study conducted an on-site investigation of Xichang Vanadium and Titanium Industrial Park to evaluate its geological disaster risk,in order to provide scientific basis for disaster prevention and reduction work in the park.The assessment results of the current geological disaster situation in the study area show that the current geological disaster situation in this area has a small degree of harm,a weak degree of development,and a low overall geological disaster risk.Based on the analysis of regional geological conditions,topography and historical disaster data,this paper further predicts and evaluates the geological disasters that may be caused by future project construction.The study found that during the project construction process,the possibility of causing geological disasters of landslides and collapses is medium,and the degree of related hazards is also medium,but the overall risk is still small.For the geological disaster of foundation pit wall landslide(collapse)and uneven foundation settlement,the possibility and degree of harm are small,and the danger is also low.However,in terms of flood impact,the engineering construction in the study area faces moderate risks,especially when the foundation pit is deeply buried,and the groundwater of the foundation pit mainly relies on the Anning River for replenishment.In order to ensure the safety of foundation pit excavation,it is recommended to take measures to strengthen precipitation during the excavation process to reduce the groundwater level to ensure stability and safety during the construction process.The results of this study provide valuable information for the prevention and control of geological disasters in similar areas,and have certain reference significance for geological disaster risk assessment under similar conditions.关键词
