豫北地区光伏发电项目建设场地地质灾害危险性研究

Study on geological hazards risk of the construction site of photovoltaic power generation project in North Henan

为了最大限度地降低地质灾害对工程建设的危害,对豫北地区光伏发电项目建设场地地质灾害危险性进行了研究,评估区主要灾种有崩塌、滑坡、地面不均匀沉陷、泥石流等,评估区地质灾害危险性评估等级为一级。对研究区地质灾害危险性现状和预测进行了评估,现状条件下评估区泥石流地质灾害发育中等,危害小,危险性小;预测评估认为,光伏板区遭受沟谷泥石流2、3、4地质灾害危险性中等,遭受坡面泥石流5、6地质灾害危险性小。划分了地质灾害危险性综合分区。研究可为后期地质灾害防治提供依据。

In order to minimize the harm of geological disasters to the project construction,this paper studied the geological disaster risk of the photovoltaic power generation project construction site in North Henan.The main types of disasters in the assessment area were collapse,landslide,uneven ground subsidence,debris flow,etc.The assessment level of the geological disaster risk in the assessment area was gradeⅠ.The current situation and prediction of geological hazards in the study area were assessed.Under the current conditions,the geological hazards of debris flow in the assessment area were moderately developed,with little harm and risk.According to the prediction and assessment,the photovoltaic panel area has a moderate risk of geological disasters caused by valley mudslides No.2,No.3,and No.4,while a low risk of geological disasters caused by slope mudslides No.5 and No.6.The comprehensive zoning of geological hazards was divided.The study provides a basis for the prevention and control of geological disasters in the later period.
