| 摘 要： | 在抽水或涌水试验管道流中，管损是普遍存在的，管损的研究对水文地质试验具有重要意义。利用黑河流域勘探孔HQ2自流井开展多落程涌水试验，并首次应用地调局水环中心自研发的九恒探头技术对不同流量自流井内长158 175 m、内径160 mm钢管的管损值进行测试。结果表明:涌水量为31 44 L/s、25 72 L/s、16 84 L/s时两探头间距长度管损值分别为2 67 m、1 70 m、0 81 m，分别占近出水口测得降深值的50 85%、48 29%、42 85%。将测试结果与经验公式计算结果进行对比分析，提出了经验公式可利用条件。

| Abstract: | In pumping tests or pour water tests, the well loss frequently occurs, and researches on pipeline resistance loss are of great significance in hydrogeological tests. In the hydrogeological survey of the Heihe River basin, an artesian well (HQ2) was used to conducted a more-routine fall test, with a new technology of the timely automatic monitoring device made by the Center for Hydrogeology and Environmental Geology Survey in Baoding, and the steel pipe resistance loss was measured within a length of 158 175 in the well of 160 mm in diameter. The results show that the loss values are 2 67 m, 1 7 m and 0 81 m, respectively, when the well discharge is 31 44 L/s, 25 72 L/s and 16 84 L/s, which account for 50 85%, 48 29% and 42 85% of the near-surface drawdown, respectively. A comparative analysis of the computation results of the empirical formula with the measured values is made, and the utilization conditions of the formula are also proposed. |
