结雅河是黑龙江左岸的重要支流,对交汇口上游的黑龙江上马厂河段水位的影响极为重要,但对上马厂站水位影响的条件和强度目前尚无定量分析结果。通过实测资料分析,确定了上马厂站水位受到结雅河顶托的必要条件是汇合后的总流量不小于9 000 m~3/s。在1988年至2008年期间,受结雅河顶托影响,上马厂水位抬高介于0.27 m到0.82 m。数学模型计算结果表明,对于上马厂较大洪水流量,当结雅河汇流比由0.03增至0.24或0.30时,上马厂站水位可抬高约0.77 m或1.43 m。
The Jialu River is an important tributary of the left bank of Heilongjiang. It is of great importance to the water level at the upper reaches of the Hemanglu plant in the upper reaches of the junction. However, there is no quantitative analysis of the conditions and intensities affecting the water level at the starting station. Through the analysis of the measured data, it is confirmed that the necessary conditions for the water level of the embarked factory to be supported by the Dingya River is that the total flow after merging is not less than 9 000 m 3 / s. During the period from 1988 to 2008, the water level of the launching plant was raised from 0.27 m to 0.82 m due to the impact of the Dingya River. The mathematical model results show that for the larger flood discharge at the start-up plant, the water level at the start-up station can be raised by about 0.77 m or 1.43 m when the confluence of the Junction Creek increases from 0.03 to 0.24 or 0.30.
