| 摘 要： | 神府东胜煤田开发建设过程中造成了大量的扰动地面,形成了新的人为水土流失。采用野外放水冲刷实验,对人为扰动地面水流的水动力学参数进行了系统研究。结果表明,流速与放水流量呈幂函数关系,在上、中、下3个断面上呈先增大后减小的变化规律;水流流态属于紊流,雷诺数与放水流量呈幂函数关系;弗劳德数值在0.59～0.88之间,Fr<1,水流属于缓流;阻力系数随坡度增加而增大;水流剪切力和水流功率分别与放水流量呈幂函数关系,并随坡度增加而增大。 |
| 关 键 词： | 神府东胜煤田 扰动地面 水动力学参数 野外放水试验 |

| Abstract: | The exploitation of the Shenfu-Dongsheng coalfield caused a large amount of disturbed lands,leading to anthropogenic soil and water loss.In this study,we investigated hydrodynamic features of the water flows through carrying out scouring experiments in the field.The results indicate that the relationship between the velocity of flow and the discharge could be well described by a power function.The flow velocities increased firstly from the upper section to the middle and then decreased from the middle secti... |
