摘　　要：本文从物理化学角度研究了荆江大堤减压井淤堵的可能性及其机理。首先对淤堵过程进行了分析,探讨了透水砂层和地下水之间的相互作用以及它们各自在产生淤堵的过程中所起的作用。最后,在弄清减压井淤堵机理的基础上对淤堵了的减压井恢复的方法提出初步看法。In this paper, the probability and the machanism of clogging of drainage wells in the Jingjiang Dyke are studied mainly from physico-chemicalstandpoint.The clogging process is investigatedfirst. The interaction between pesvious sand layerand groundwater and their contribution to cloggingprocess are discussed. Based on the studied: resultsof clogging machanism, the rahabilitation methodof the. clogged drainage well is propsoed.
