| 摘 要： | 影响半径是一个有争议的概念，针对不同含水层和计算模型各有不同的计算方式，而在工程应用中常使用理论依据不甚明确的经验公式。针对可形成稳定流的越流承压含水层，展开对确定其影响半径的常用方法即3个及以上观测孔稳定流阶段降深-距离直线图解法的分析，认为这一方法容易造成工程师对影响半径的误判，指出其易于误读之处并对使用该法提出了修正建议。

| Abstract: | The influential radius is a controversial conception.For different aquifer conditions and concept models,there are distinct methods to calculate the influential radius.The empirical formulas,which lack of strict theoretical basis,are more popular in practice.The routine method to ascertain the influential radius in leaky confined aquifer is stretching the s-log(r) line through three or more observation holes in steady flow to find the zero-drawdown distance.The method may bring misunderstanding to engineers... |
