开都河河道渗漏规律实验研究

Experimental study on law of Kaidu river seepage

采用电子水尺系统的监测了开都河各计算断面水位变化过程,计算了水位传播时间,考虑了河流非稳定流状态,用河道水量平衡法计算了渗漏量,分析了渗漏规律。实验结果表明:(1)大山口水文站至218国道断面水位传播时间4~5 h;218国道断面至21团大桥断面水位传播时间11~12 h;21团大桥断面至焉耆大桥断面水位传播时间6 h;焉耆大桥断面至宝浪苏木断面,水位传播时间5 h。(2)开都河多年平均年径流量35.18×10^(8)m^(3),河道引水量11.82×10^(8)m^(3),河道损失量4.66×10^(8)m^(3)。大山口水文站至21团大桥河段,以地下水补给河水为主;21团大桥至宝浪苏木大桥河段,以河水补给地下水为主。

This paper monitoring the water level of Kaidu River computation cross-sections by electronic gauge systemati⁃cally,calculating its propagation time,considering unsteady flow states,calculating its seepage with the river water balance method,and analyzing its law.The results show that:(1)river section which from Dashankou hydrological station to 218 Na⁃tional Road,propagation time is 4~5 hours,from 218 National Road to 21 Tuan Bridge,propagation time is 11~12 hours,from 21 Tuan Bridge to Yanqi Bridge,propagation time is 6 hours,from Yanqi Bridge to Baolangsumu section,propagation time is 5 hours.(2)Kaidu River average annual runoff is 35.18×10^(8)m^(3),river water diversion is 11.82×10^(8)m^(3),seepage is 4.66×10^(8)m^(3).River section which from Dashankou hydrological station to 21 Tuan Bridge,transformation mainly is groundwater recharge river,river section which from 21 Tuan Bridge to Baolangsumu section,transformation mainly is river re⁃charge groundwater.
