潮汐作用下滨海地下卤水开采区水盐迁移模式及影响因素
Tidal-Driven Water-Salt Transport Dynamics in Coastal Subsurface Brine Mining Zones
摘要
Abstract
This study mainly focuses on the laws governing the replenishment of coastal subsurface brine with marine-derived salts.Taking Yangkou Saltworks in Laizhou Bay as a case study,we integrat-ed field monitoring with numerical modeling.Fieldwork included electrical resistivity tomography(ERT)and groundwater multi-parameter measurements across tidal cycles.The established hydrogeo-logical model simulated water-salt migration under tidal influence.Results demonstrate a dual-peak sa-linity supply pattern.Larger tidal ranges advanced the first salinity peak by 1 h while reducing peak con-centration by 0.2～0.3 g/L.Cessation of brine mining triggered seawater intrusion and salinity loss.Tidal creek networks were identified as critical pathways for the first salinity peak formation.Key find-ings reveal that tidal dynamics control the phreatic brine salinity variation amplitude.The high-permea-bility tidal creek system enables rapid salt transport.Subsurface brine mining activities dominate the land-sea hydraulic gradient.This study provides theoretical support for optimizing brine resource man-agement in coastal zones.关键词
