| 中文摘要: |
| 描述了非完整沟(管)工程布设形式和补给出流条件，对现行的平原区截渗排水渗流计算方法进行了综合分析，针对单、双沟的对称和非对称布设形式，提出了系列的有限含水层厚度条件下，对称与非对称单、双沟截渗排水的渗流水动力学计算公式。计算结果表明，在补给和出流条件基本相同的情况下，双沟比单沟截取地下水量和降低地下水位的作用都明显增大。 |
| 英文摘要: |
| The engineering layout, recharge and drainage condition of partial penetrated ditches in plain area are described and the current used methods for calculating the seepage flow to draining ditches for intercepting ground water are comprehensively discussed. A series of formulas based on hydrodynamics for calculating the symmetrical
or unsymmetrical seepage of single ditch or double ditch under the condition of limited aquifer thickness are suggested. The calculation result shows that the double ditch is more effective than single ditch in intercepting groundwater and lowering water table under condition of the same recharge and discharge. |
