摘要
在大厚度含水层中设计管井时,合理确定滤水管长度,对于经济有效地开发利用地下水资源,有很大实际意义。本文提出了“滤水管实用长度”及确定管井‘滤水管实用长度”的“出水量增长率选择法”和“效益—成本分析法”,对指导生产井设计具有一定的实用价值。
In the design of tube well embedded in aquifer of large thickness, the rational determination of the length of well screen is of vital practical importance for the economically effective development and utilization of groudwater resource. The following topics are presented in this paper: 'the practical length of well screen', 'the choice method of increasing rate of well yield', 'the method of benefit—cost analysis'. The latter two are methods to determine the well screen length. These are of practical importance to guide the design of water-wells.
