| 摘 要： | 通过水槽试验,结合理论分析,研究丁坝附近的动水总压力和脉动压力的分布情况,绘出总压力和脉动压力的等值线分布图。把丁坝附近区域分成4个测压区进行研究,详细分析了各个测压区的总压力和脉动压力的分布规律。进一步研究坝长、流量及水深对丁坝附近脉动压力分布的影响,并分析其原因。 |
| 关 键 词： | 丁坝 动水总压力 脉动压力 等值线 |

| Abstract: | With the aid of the model experiment and the method of theoretical analysis,we analyze the distribution disciplinarian of gross dynamic hydraulic pressure and fluctuating pressure near the spur dike.After drawing the distribution isoline of fluctuation pressure,we divide the area near the spur dike into four areas for the measure pressure,and explore the distribution disciplinarian of gross dynamic hydraulic pressure and fluctuating pressure.The influential factors such as the length of spur dike,flux and depth of flow are also analyzed. |
| Keywords: | spur dike gross dynamic hydraulic pressure fluctuation pressure isoline |
