摘要
三维可视化模型可以更加直观、更加全面地展示土壤中污染物的分布情况和土壤污染范围、方量。以河北省某搬迁厂房为研究对象,利用EVS2020软件进行三维可视化建模。针对场地中的地层性质和总砷含量建立三维可视化模型,选用克里格(Kriging)插值方法,并分析总砷的分布规律和污染程度,验证模型精度。研究表明:土壤总砷超标地块集中于污水处理厂所在区域,污染方量为77463.19 m^(3)。三维空间模型的应用为今后土壤状况调查、土壤风险管控和土壤修复工作的开展提供有力的技术支持。
The three-dimensional visualization model can more intuitively and comprehensively display the distribution of pollutants in soil,the scope and quantity of soil pollution.Taking a relocation plant in Hebei Province as the research object,the three-dimensional visual modeling was carried out by using evs2020 software.A three-dimensional visualization model is established according to the formation properties and total arsenic content in the site,Kriging interpolation method is selected,and the distribution law and pollution degree of total arsenic are analyzed to verify the accuracy of the model.The study shows that the plots with total arsenic in the soil exceeding the standard are concentrated in the area where the sewage treatment plant is located,and the pollution volume is 77463.19 cubic meters.The application of three-dimensional spatial model provides strong technical support for the future soil condition investigation,soil risk control and soil remediation.
