基于同期的外海潮位与S-1监测井电导率监测数据,对辽东湾西侧绥中砂质平原海水入侵岸段的外海潮位对海水入侵的影响进行了分析。结果表明外海潮位的变化可以对海水严重入侵区域的S-1监测井附近产生显著的影响,高潮位时会导致该地区海水入侵程度加重。基于实测的过渡区地下水位与Cl-含量数据,得出季节变化的地下水位与季节变化的地下水Cl-含量呈现明显的正相关关系,相关系数在0.92以上。利用该相关关系,可以得出该地区的海水入侵过渡区(250 mg/L)对应的地下水位值为-2.22 m~0.25 m,可以为确立该地区海水入侵过渡断面的位置提供间接的依据和参考。
Based on the monitoring data of the open sea tide and the S-1 monitoring well in the same period, the influence of the open sea tide on the seawater intrusion in the offshore section of the Suizhong sandy plains on the west of Liaodong Bay was analyzed. The results show that the change of the tidal position outside the sea can have a significant impact on the vicinity of the S-1 monitoring well in the area where the seawater is seriously invaded. When the tide level is high, the degree of seawater intrusion will be aggravated. Based on the measured data of groundwater level and Cl-content in the transitional area, it is found that there is a clear positive correlation between the seasonal variation of groundwater level and the seasonal variation of groundwater Cl-content, with a correlation coefficient above 0.92. Using this correlation, it can be concluded that the corresponding groundwater level in the transition zone (250 mg / L) is -2.22 m ~ 0.25 m, which can provide an indirect basis for establishing the location of the transitional section of seawater intrusion in the area. reference.
