黄山区某国道改扩建工程地质灾害危险性评估

Assessment of Geological Hazard Risk of a National Highway Reconstruction and Expansion Project in Huangshan District

以黄山区某国道改扩建工程为例,通过对工程建设区的现场调查与收集资料,查明工程建设区的地质环境条件基本特征,对工程建设区进行现状评估、预测评估、综合评估,分析工程建设区各种地质灾害的危险性,根据评估区地质环境条件、现状评估及预测评估结果,结合评估区地质灾害的量化评估标准,该次评估划分为3个区,即崩塌、滑坡地质灾害小区(I-1),崩塌地质灾害危险性小区(I-2)和崩塌、岩溶塌陷地质灾害危险性小区(I-3),提出防治地质灾害的措施和建议,并做出建设场地适宜性评价。

Taking the reconstruction and expansion project of a national highway in Huangshan District as an example,through the on-site investigation and data collection of the project construction area,the basic characteristic of the geological environment conditions in the project construction area is identified,the status quo assessment,forecast assessment and comprehensive assessment of the project construction area are carried out,and the risk of various geological disasters in the project construction area is analyzed.According to the results of geological environment conditions and current situation assessment and forecast assessment in the assessment area,combined with the quantitative assessment standard of geological disasters in the assessment area,this assessment is divided into three areas,namely the collapse and landslide geological disaster zone(I-1),geological disaster risk zone of collapse(I-2)and geological disaster risk zone of collapse and karst collapse(I-3),puts forward measures and suggestions for prevention and control of geological disasters,and evaluates the suitability of the construction site.
