摘　　要：根据河流一级阶地(含高漫滩)水文地质结构的特殊性,分析河槽型和平原型水库蓄水后两岸地下水动力条件的变化,提出一级阶地宜采用承压水计算模式预测两岸地下水雍高;论证岸后承压渗流场作用下形成的浸没实质是黏性土盖层的"弱结合水浸没"。同时,针对浸没区承压渗流和"弱结合水浸没"特征,分析了常见的治理措施存在的问题,提出了改进治理建议。The variation of the underground hydraulic conditions after the water storage in the channel storage reservoir and plain reservoir has been analyzed with the reference to the unique hydrological and geological structures of the first terrace of the river （ high valley flat section）. It is suggested that the confined water pressure be used to predict the affluent level. It has been proved that the inundation by the seepage flow field pressure can be defined as ＂ the weak bonding inundation＂ . The analysis of the problems in the regular treatment measures has been done with the reference of the pressure seepage flow field and the weak bonding inundation situation, and improvement measures have been figured out.
