The result shows that with the same AS pressure and airflow rate,the greater the AS well depth,the greater the radius of influence(ROI),but the air distribution concen.

实验结果表明:在相同曝气压力和流量下,曝气深度越大,影响半径越大,但影响区内的气流分布越稀疏;相反,曝气深度越小,则曝气影响半径越小,但在影响区内空气流线分布越密。

Related parameters in rechecking formula to the dewatering of foundation pit have been discussed,the selection of related parameter should consider the radius of influence of pumping we.

干扰群井基坑降水设计中,对基坑内水位降深的复核是关键的一步,它关系到降水井布置的合理性、影响到降水井的数量及基坑降水的成败,该文针对基坑内地下水位复核公式中相关参数的选取进行了分析,探讨了具体参数取值的合理性问题,认为相关参数的选取应该考虑到抽水井的影响半径,公式中的基坑涌水量应该为抽水井影响半径范围内所有抽水井的出水量,分析了参数的使用条件,并结合实际情况提出了改进建议,新参数的取值方法更符合实际情况。
