| 中文摘要: |
| 本文在示踪剂质量守恒的基础上，考虑其弥散作用，采用单孔测试技术，推导了含水层水平流速计算公式并求解。最后，应用于工程实例结果表明，当存在较强的垂向流时，弥散作用对水平流速计算结果影响很大，不可忽略。 |
| 英文摘要: |
| According to the principle of mass conservation for tracer, the formula for calculating horizontal velocity in aquifer is deduced by adopting the single test well technology and considering the dispersion effect. The application of this method indicates that the horizontal flow velocity significantly affects the calculation result when strong vertical flow exists, so that the dispersion effect can not be ignored. |
