问题的提出为水工建設作水文地質調查时,通常作水下勘探,用抽水实驗来了解河床冲积的渗透系数。苏联学者巴布什金和阿波拉莫夫曾經研究了均質冲极层中的潛水向不完整井流动的情况,在生产实踐中已經广泛的应用了他們的研究成果,水文地質家們就是应用以巴布什金为名的“河床下的不完整井”流量公式来确定冲积层的渗透系数。但实际 PROBLEM PROBLEMS When performing hydrogeological surveys for hydraulic construction, it is common practice to conduct submarine surveys and use pumping experiments to understand the permeability coefficients of riverbed alluvial deposits. Soviet scholar Babushkin and Abomeamov have studied the flow of submersibles into homogeneous wells in a homogeneous redosphere, and their results have been widely used in production practice, and hydrogeologists have applied Babushkin, under the pseudowire “imperfect channel under the riverbed,” is used to determine the permeability coefficient of the alluvium. But actually
