摘　　要：基于攀枝花地区某场地为例,通过工程场地地震安全性评价标准建立工程场地地震地质灾害评价体系,在该评价体系上进行近23个地质灾害调查点现场地震地质灾害现场调查,并结合坡度、峰值加速度,岩土体性状计算,得到不同工况下地震地质灾害危险程度等级。为地震引起地质灾害可能性及潜在危害性研究评价及尾矿库建设提供工程地质数据。Taking a site in Panzhihua area as an example,a seismic geological hazard evaluation system for engineering sites was established based on the seismic safety evaluation standards.Nearly 23 geological hazard points were surveyed on-site based on this evaluation system.Combined with slope,peak acceleration,and rock and soil properties calculation,the risk level of seismic geological hazards under different working conditions was calculated.The results provide engineering geological data for the study and evaluation of the possibility and potentialharmfulness of geological disasters caused by earthquakes,as well as for the construction of tailings reservoirs.
