利用国家863课题支持研制的电阻率探杆自动监测系统,分别进行了海水入侵、地下水位升降、土壤盐渍化过程的动态监测室内模拟实验,旨在探讨该系统用于海水入侵、地下水位变化、土壤盐渍化等环境过程自动监测的可行性。结果表明,海水入侵形成的咸-淡水界面及海水弥散带,地下水位位置上下及包气带,及不同含盐量的土体,均具有显著的电阻率探杆测试结果特征差异。该系统可为海水入侵,地下水位变化,土壤盐渍化,土壤地下污染等环境过程的原位连续实时自动监测提供数据资料及技术支持。
Based on the automatic resistivity probe monitoring system developed by national 863 project, the indoor simulation experiments of dynamic monitoring of seawater intrusion, groundwater level rise and soil salinization were carried out respectively. The purpose of this study was to explore the application of this system to seawater intrusion and groundwater level change , Soil salinization and other environmental processes automatically monitor the feasibility. The results show that saltwater-freshwater interface and seawater diffusion zone formed by seawater intrusion, groundwater level above and below the aeration zone and soil with different salt content have significant differences in characteristics of the resistivity probe test results. The system can provide data and technical support for in situ continuous real-time automatic monitoring of environmental processes such as seawater intrusion, groundwater level change, soil salinization and soil underground pollution.
