基于信息量和Newmark模型的地震地质灾害危险性评价——以安徽省六安市霍山县落儿岭地区为例

Assessment of the danger of geological hazard of earthquake based on information content and Newmark model:An example from the Luoerling area of Huoshan County,Lu’an City,Anhui Province

评价区属于安徽省地质灾害高发区,也是华东地区地震活动较为频繁区之一。本文以霍山县典型区域——落儿岭区为研究区,选取评价因子,分别开展基于信息量模型和Newmark模型的地震地质灾害危险性评价,并综合二者的结果,根据所得结果基于斜坡单元进行危险性分区,将研究区的地震地质灾害危险区分为三个等级:低危险区、中危险区和高危险区,以期为该区城镇规划建设和地质灾害防治规划提供参考。

The assessed area lies where high incidences of geological hazards take place in Anhui Province and is one with frequent seismic activities in East China.Focusing on the Luoerling area,a typical area in Huoshan County,this paper selects relevant factors to carry out the earthquake hazard danger assessment based on the information content model and Newmark model,respectively,combine the results of both,and then divides the earthquake hazard danger zones in the study area into three levels based on slope unit,i.e.,low danger area,medium danger area and high danger area,in order to provide a reference for urban planning and construction,and geological hazard control planning in this area.
