摘要
提出一种工程地质勘测过程中土壤污染治理约束优化模型,通过空间分层技术构建土壤空间抽样优化模型,抽取工程地质勘测过程中的土壤样本。根据重金属迁移影响因素得到土壤污染源位置确定模型,确定土壤污染源的位置,并构建土壤污染综合评价模型对土壤污染源的污染程度进行评价,根据评价结果选择对应的治理方案,完成工程地质勘测过程中的土壤污染治理。所提方法可准确的确定污染源的位置,并准确的完成污染源污染程度的评价。
An optimization model of soil pollution control is proposed in the process of engineering geological survey, and the soil spatial sampling optimization model is constructed by spatial stratification technology. Soil samples in the process of engineering geological survey are extracted. According to the influence factors of heavy metal migration, the location of soil pollution source is determined, the position of soil pollution source is determined, and the comprehensive evaluation model of soil pollution is constructed to evaluate the pollution degree of soil pollution source. The corresponding treatment scheme is selected according to the evaluation results, and the soil pollution control in the process of engineering geological survey is completed.. The experimental results show that the proposed method can accurately determine the location of pollution sources and accurately evaluate the pollution degree of pollution sources.
